  • Apache Atlas安装和配置

    Atlas概述

    Apache Atlas为组织提供开放式元数据管理和治理功能,用以构建其数据资产目录,对这些资产进行分类和管理,并为数据分析师和数据治理团队,提供围绕这些数据资产的协作功能。

     Atlas架构原理

     

    Atlas安装及使用

    1)Atlas官网地址:https://atlas.apache.org/

    2)文档查看地址:https://atlas.apache.org/0.8.4/index.html

    3)下载地址:https://www.apache.org/dyn/closer.cgi/atlas/0.8.4/apache-atlas-0.8.4-sources.tar.gz

    通常企业开发中选择集成外部的HBase+Solr,方便项目整体进行集成操作。

    安装Solr5.2.1

    1)Solr版本要求必须是5.2.1,见官网
    
    2)Solr下载:http://archive.apache.org/dist/lucene/solr/5.2.1/solr-5.2.1.tgz
    
    4)解压solr-5.2.1.tgz到/opt/module/目录下面
      [kris@hadoop101 module]$ tar -zxvf solr-5.2.1.tgz -C /opt/module/
    
    5)修改solr-5.2.1的名称为solr
      [kris@hadoop101 module]$ mv solr-5.2.1/ solr
    
    6)进入solr/bin目录,修改solr.in.sh文件
      [kris@hadoop102 solr]$ vim bin/solr.in.sh
    
    #添加下列指令
    ZK_HOST="hadoop101:2181,hadoop102:2181,hadoop103:2181"
    SOLR_HOST="hadoop101"
    # Sets the port Solr binds to, default is 8983
    #可修改端口号
    SOLR_PORT=8983
    
    7)分发Solr,进行Cloud模式部署
      [kris@hadoop101 module]$ xsync solr
        提示:分发完成后,分别对hadoop102、hadoop103主机/opt/module/solr/bin下的solr.in.sh文件,修改为SOLR_HOST=对应主机名。
    
    8)在三台节点上分别启动Solr,这个就是Cloud模式
      [kris@hadoop101 solr]$ bin/solr start
      [kris@hadoop102 solr]$ bin/solr start
      [kris@hadoop103 solr]$ bin/solr start
      提示:启动Solr前,需要提前启动Zookeeper服务。
    
    9)Web访问8983端口,可指定三台节点中的任意一台IP,http://hadoop101:8983/solr/#/ 
      提示:UI界面出现Cloud菜单栏时,Solr的Cloud模式才算部署成功。
    
    10)编写Solr启动停止脚本
      (1)在hadoop101的/home/kris/bin目录下创建脚本
       [kris@hadoop102 bin]$ vim s.sh
       在脚本中编写如下内容
    #!/bin/bash
    case $1 in
    "start"){
        for i in hadoop101 hadoop102 hadoop103
        do
            ssh $i "/opt/module/solr/bin/solr start"
        done
    };;
    "stop"){
        for i in hadoop101 hadoop102 hadoop103
        do
            ssh $i "/opt/module/solr/bin/solr stop"
        done
    };;
    esac
    View Code
    2)增加脚本执行权限
        [kris@hadoop101 bin]$ chmod +x s.sh3)Solr集群启动脚本
        [kris@hadoop101 module]$ s.sh start
      (4)Solr集群停止脚本
        [kris@hadoop101 module]$ s.sh stop

    安装Atlas0.8.4

    1)解压apache-atlas-0.8.4-bin.tar.gz到/opt/module/目录下面
       [kris@hadoop101 module]$ tar -zxvf apache-atlas-0.8.4-bin.tar.gz -C /opt/module/
    
    2)修改apache-atlas-0.8.4的名称为atlas
       [kris@hadoop101 module]$ mv apache-atlas-0.8.4/ atlas

    Atlas集成外部框架

    Atlas集成Hbase

    1)进入/opt/module/atlas/conf/目录,修改配置文件
    [kris@hadoop101 conf]$ vim atlas-application.properties
    #修改atlas存储数据主机
    atlas.graph.storage.hostname=hadoop101:2181,hadoop102:2181,hadoop103:2181
    
    2)进入到/opt/module/atlas/conf/hbase路径,添加Hbase集群的配置文件到${Atlas_Home}
    [kris@hadoop101 hbase]$
    ln -s /opt/module/hbase/conf/ /opt/module/atlas/conf/hbase/
    
    3)在/opt/module/atlas/conf/atlas-env.sh中添加HBASE_CONF_DIR
    [kris@hadoop101 conf]$ vim atlas-env.sh
    #添加HBase配置文件路径
    export HBASE_CONF_DIR=/opt/module/atlas/conf/hbase/conf

     Atlas集成Solr

    1)进入/opt/module/atlas/conf目录,修改配置文件
    [kris@hadoop101 conf]$ vim atlas-application.properties
    #修改如下配置
    atlas.graph.index.search.solr.zookeeper-url=hadoop101:2181,hadoop102:2181,hadoop103:2181
    
    2)将Atlas自带的Solr文件夹拷贝到外部Solr集群的各个节点。
    [kris@hadoop101 conf]$
     cp -r /opt/module/atlas/conf/solr /opt/module/solr/
    
    3)进入到/opt/module/solr路径,修改拷贝过来的配置文件名称为atlas_conf
    [kris@hadoop101 solr]$ mv solr atlas_conf
    
    4)在Cloud模式下,启动Solr(需要提前启动Zookeeper集群),并创建collection
    [kris@hadoop101 solr]$ bin/solr create -c vertex_index -d /opt/module/solr/atlas_conf -shards 3 -replicationFactor 2
    [kris@hadoop101 solr]$ bin/solr create -c edge_index -d /opt/module/solr/atlas_conf -shards 3 -replicationFactor 2
    [kris@hadoop101 solr]$ bin/solr create -c fulltext_index -d /opt/module/solr/atlas_conf -shards 3 -replicationFactor 2
    
    -shards 3:表示该集合分片数为3
    -replicationFactor 2:表示每个分片数都有2个备份
    vertex_index、edge_index、fulltext_index:表示集合名称
    注意:如果需要删除vertex_index、edge_index、fulltext_index等collection可以执行如下命令。
    [kris@hadoop101 solr]$ bin/solr delete -c ${collection_name}
    创建collection的详细如下:
    [kris@hadoop101 solr]$ bin/solr create -c vertex_index -d /opt/module/solr/atlas_conf -shards 3 -replicationFactor 2
    Connecting to ZooKeeper at hadoop101:2181,hadoop102:2181,hadoop103:2181
    Uploading /opt/module/solr/atlas_conf for config vertex_index to ZooKeeper at hadoop101:2181,hadoop102:2181,hadoop103:2181
    
    Creating new collection 'vertex_index' using command:
    http://hadoop103:8983/solr/admin/collections?action=CREATE&name=vertex_index&numShards=3&replicationFactor=2&maxShardsPerNode=2&collection.configName=vertex_index
    
    {
      "responseHeader":{
        "status":0,
        "QTime":5435},
      "success":{"":{
          "responseHeader":{
            "status":0,
            "QTime":5094},
          "core":"vertex_index_shard1_replica1"}}}
    
    [kris@hadoop101 solr]$ bin/solr create -c edge_index -d /opt/module/solr/atlas_conf -shards 3 -replicationFactor 2
    Connecting to ZooKeeper at hadoop101:2181,hadoop102:2181,hadoop103:2181
    Uploading /opt/module/solr/atlas_conf for config edge_index to ZooKeeper at hadoop101:2181,hadoop102:2181,hadoop103:2181
    
    Creating new collection 'edge_index' using command:
    http://hadoop103:8983/solr/admin/collections?action=CREATE&name=edge_index&numShards=3&replicationFactor=2&maxShardsPerNode=2&collection.configName=edge_index
    
    {
      "responseHeader":{
        "status":0,
        "QTime":3280},
      "success":{"":{
          "responseHeader":{
            "status":0,
            "QTime":3116},
          "core":"edge_index_shard3_replica2"}}}
    
    [kris@hadoop101 solr]$ bin/solr create -c fulltext_index -d /opt/module/solr/atlas_conf -shards 3 -replicationFactor 2
    Connecting to ZooKeeper at hadoop101:2181,hadoop102:2181,hadoop103:2181
    Uploading /opt/module/solr/atlas_conf for config fulltext_index to ZooKeeper at hadoop101:2181,hadoop102:2181,hadoop103:2181
    
    Creating new collection 'fulltext_index' using command:
    http://hadoop103:8983/solr/admin/collections?action=CREATE&name=fulltext_index&numShards=3&replicationFactor=2&maxShardsPerNode=2&collection.configName=fulltext_index
    
    {
      "responseHeader":{
        "status":0,
        "QTime":3455},
      "success":{"":{
          "responseHeader":{
            "status":0,
            "QTime":3115},
          "core":"fulltext_index_shard3_replica1"}}}

    5)验证创建collection成功
    登录solr web控制台:http://hadoop101:8983/solr/#/~cloud 看到如下图显示:

    Atlas集成Kafka

    1)进入/opt/module/atlas/conf/目录,修改配置文件atlas-application.properties
    [kris@hadoop101 conf]$ vim atlas-application.properties
    #########  Notification Configs  #########
    atlas.notification.embedded=false
    atlas.kafka.zookeeper.connect=hadoop101:2181,hadoop102:2181,hadoop103:2181
    atlas.kafka.bootstrap.servers=hadoop101:9092,hadoop102:9092,hadoop103:9092
    atlas.kafka.zookeeper.session.timeout.ms=4000
    atlas.kafka.zookeeper.connection.timeout.ms=2000
    atlas.kafka.enable.auto.commit=true
    
    2)启动Kafka集群,并创建Topic
    [kris@hadoop101 kafka]$ bin/kafka-topics.sh --zookeeper hadoop101:2181,hadoop102:2181,hadoop103:2181 --create --replication-factor 3 --partitions 3 --topic _HOATLASOK
    
    [kris@hadoop101 kafka]$ bin/kafka-topics.sh --zookeeper hadoop101:2181,hadoop102:2181,hadoop103:2181 --create --replication-factor 3 --partitions 3 --topic ATLAS_ENTITIES

     Atlas其他配置

    1)进入/opt/module/atlas/conf/目录,修改配置文件atlas-application.properties
    [kris@hadoop101 conf]$ vim atlas-application.properties
    #########  Server Properties  #########
    atlas.rest.address=http://hadoop101:21000
    # If enabled and set to true, this will run setup steps when the server starts
    atlas.server.run.setup.on.start=false
     
    #########  Entity Audit Configs  #########
    atlas.audit.hbase.zookeeper.quorum=hadoop101:2181,hadoop102:2181,hadoop103:2181
    
    2)记录性能指标,进入/opt/module/atlas/conf/路径,修改当前目录下的atlas-log4j.xml
    [kris@hadoop101 conf]$ vim atlas-log4j.xml
    #去掉如下代码的注释
    <appender name="perf_appender" class="org.apache.log4j.DailyRollingFileAppender">
        <param name="file" value="${atlas.log.dir}/atlas_perf.log" />
        <param name="datePattern" value="'.'yyyy-MM-dd" />
        <param name="append" value="true" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d|%t|%m%n" />
        </layout>
    </appender>
    <logger name="org.apache.atlas.perf" additivity="false">
        <level value="debug" />
        <appender-ref ref="perf_appender" />
    </logger>

     Atlas集成Hive

    1)进入/opt/module/atlas/conf/目录,修改配置文件atlas-application.properties
    [kris@hadoop101 conf]$ vim atlas-application.properties
    
    ######### Hive Hook Configs #######
    atlas.hook.hive.synchronous=false
    atlas.hook.hive.numRetries=3
    atlas.hook.hive.queueSize=10000
    atlas.cluster.name=primary
    
    2)将atlas-application.properties配置文件加入到atlas-plugin-classloader-1.0.0.jar中
    [kris@hadoop101 hive]$ zip -u /opt/module/atlas/hook/hive/atlas-plugin-classloader-0.8.4.jar /opt/module/atlas/conf/atlas-application.properties
    
    [kris@hadoop101 hive]$ cp /opt/module/atlas/conf/atlas-application.properties /opt/module/hive/conf/
    
    原因:这个配置不能参照官网,将配置文件考到hive的conf中。参考官网的做法一直读取不到atlas-application.properties配置文件,
    看了源码发现是在classpath读取的这个配置文件,所以将它压到jar里面。
    3)在/opt/module/hive/conf/hive-site.xml文件中设置Atlas hook [kris@hadoop101 conf]$ vim hive-site.xml <property> <name>hive.exec.post.hooks</name> <value>org.apache.atlas.hive.hook.HiveHook</value> </property> [kris@hadoop101 conf]$ vim hive-env.sh #在tez引擎依赖的jar包后面追加hive插件相关jar包 export HIVE_AUX_JARS_PATH=/opt/module/hadoop-2.7.2/share/hadoop/common/hadoop-lzo-0.4.20.jar$TEZ_JARS,/opt/module/atlas/hook/hive/atlas-plugin-classloader-0.8.4.jar,/opt/module/atlas/hook/hive/hive-bridge-shim-0.8.4.jar

     

     将Hive元数据导入Atlas

    1)配置Hive环境变量
    [kris@hadoop101 hive]$ sudo vim /etc/profile
    #配置Hive环境变量
    export HIVE_HOME=/opt/module/hive
    export PATH=$PATH:$HIVE_HOME/bin/
    
    [kris@hadoop101 hive]$ source /etc/profile
    
    2)启动Hive,如果Hive能正常启动说明环境OK,就可以退出Hive客户端
    
    [kris@hadoop101 hive]$ hive
    hive (default)> show databases;
    hive (default)> use gmall;
    
    3)在/opt/module/atlas/路径,将Hive元数据导入到Atlas
    [kris@hadoop101 atlas]$ bin/import-hive.sh
    Using Hive configuration directory [/opt/module/hive/conf]
    Log file for import is /opt/module/atlas/logs/import-hive.log
    log4j:WARN No such property [maxFileSize] in org.apache.log4j.PatternLayout.
    log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.PatternLayout.
    输入用户名:admin;输入密码:admin Enter username
    for atlas :- admin Enter password for atlas :- Hive Meta Data import was successful!!!

     在Hive中创建test库,total_amount_result表:刷新页面即可实时展示出来:

    hive (default)> create database test;
    OK
    Time taken: 0.034 seconds
    hive (default)> use test;
    OK
    Time taken: 0.019 seconds
    hive (test)> CREATE EXTERNAL TABLE total_amount_result(
               >   `order_id` int,
               >   `update_time` string,
               >   `deal_total_amount` double
               > )row format delimited fields terminated by ','
               > ;
    OK
    View Code

     必须得跑个脚本任务atlas它才知道依赖关系,历史数据它不知道;

       执行ads_gmv.sh脚本:

     表之间的血缘图:

    Lineage血缘图、Audits记录修改时间等详情信息

     

    字段的血缘图:

    Rest API使用(二次开发使用)

      如果需要对Atlas进行二次开发,可以查看官网地址,https://atlas.apache.org/api/v2/index.html,根据官方API进行二次开发。
