  • 基于Hadoop3.1.2集群的Hive3.1.2安装(有不少坑)

    1. 前置条件: 已经安装好了带有HDFS, MapReduce, Yarn 功能的 Hadoop集群

      链接: ubuntu18.04.2 hadoop3.1.2+zookeeper3.5.5高可用完全分布式集群搭建

    2. 上传tar包并解压到指定目录:

      tar -zxvf apache-hive-3.1.2-bin.tar.gz -C /opt/ronnie

    3. 修改hive配置文件:

      • 新建文件夹

        mkdir /opt/ronnie/hive-3.1.2/warehouse
hadoop fs -mkdir -p /opt/ronnie/hive-3.1.2/warehouse
hadoop fs -chmod 777 /opt/ronnie/hive-3.1.2/warehouse
hadoop fs -ls /opt/ronnie/hive-3.1.2/

      • 复制配置文件

        cd /opt/ronnie/hive-3.1.2/conf
cp hive-exec-log4j2.properties.template hive-exec-log4j2.properties
cp hive-log4j2.properties.template hive-log4j2.properties
cp hive-default.xml.template hive-default.xml
cp hive-default.xml.template hive-site.xml
cp hive-env.sh.template hive-env.sh

    • 修改环境配置文件

      vim hive-env.sh

HADOOP_HOME=/opt/ronnie/hadoop-3.1.2
export HIVE_CONF_DIR=/opt/ronnie/hive-3.1.2/conf
export HIVE_AUX_JARS_PATH=/opt/ronnie/hive-3.1.2/lib

      • vim hive-site.xml修改配置文件

        • 这时候先回顾一下vim操作(由于这个文件页数比较多...):

          • gg: 到页首

          • G: 到页末

          • 22, 6918 d(在此执行的删行操作)

          • 修改配置文件参数:

            <configuration>
  <property>
          <name>javax.jdo.option.ConnectionUserName</name>
          <value>root</value>
  </property>
  <property>
          <name>javax.jdo.option.ConnectionPassword</name>
          <!--你的Mysql数据库密码--> 
          <value>xxxxxxx</value> 
  </property>
  <property>
          <name>javax.jdo.option.ConnectionURL</name>
          <value>jdbc:mysql://192.168.180.130:3306/hive?allowMultiQueries=true&amp;useSSL=false&amp;verifyServerCertificate=false</value>
  </property>
  <property>
          <name>javax.jdo.option.ConnectionDriverName</name>
          <value>com.mysql.jdbc.Driver</value>
  </property>
    <property>
        <name>datanucleus.readOnlyDatastore</name>
        <value>false</value>
    </property>
    <property>
        <name>datanucleus.fixedDatastore</name>
        <value>false</value>
    </property>
    <property>
        <name>datanucleus.autoCreateSchema</name>
        <value>true</value>
    </property>
    <property>
        <name>datanucleus.autoCreateTables</name>
        <value>true</value>
    </property>
    <property>
        <name>datanucleus.autoCreateColumns</name>
        <value>true</value>
    </property>
</configuration>

    1. 下载jdbc

      cd /home/ronnie/soft
wget http://mirrors.163.com/mysql/Downloads/Connector-J/mysql-connector-java-5.1.48.tar.gz

    2. MySQL设置

      • 下载:

        sudo apt-get install mysql

      • mysql -uroot 进入mysql界面(Ubuntu mysql 下载后默认开机自启, Centos的话还需要service start mysqld 一下)

      • 修改密码:

        • 查看用户及密码:

          • 老版本:

            use mysql;
select host,user,password from mysql.user;

          • 我用的5.7版本

            use mysql;
select user, host, authentication_string from user;

        • 设置新密码

          update mysql.user set authentication_string='你要设置的密码' where user='root';

      • 这边有一个巨坑, 初始化数据库的时候报的:

        org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version.
Underlying cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException : Communications link failure

        • 连接的问题, 但是grant all on hive.* to root@'%' identified by 'xxxxxx'; 敲了好几次都没用。

          mysql> select user, authentication_string, host from user;
+------------------+-------------------------------------------+-----------+
| user             | authentication_string                     | host      |
+------------------+-------------------------------------------+-----------+
| root             |                                           | localhost |

+------------------+-------------------------------------------+-----------+

          • 发现有重复的root用户, 删掉, 直接将root修改为%

            delete from user where host = '%';
mysql> select user, authentication_string, host from user;
+------------------+-------------------------------------------+-----------+
| user             | authentication_string                     | host      |
+------------------+-------------------------------------------+-----------+
| root             |                                           | localhost |

+------------------+-------------------------------------------+-----------+

          • 重启服务:

            service mysqld restart

          • 还是报错......, 测试了一下远程navicat也连不上, 报的1251

          • vim /etc/mysql/mysql.conf.d/mysqld.cnf 把其中的bind-address改为0.0.0.0

          • 还是报错, 最终的解决方案:

            ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '密码';
#记得提交
FLUSH PRIVILEGES;

        • 然后就连上navicat了, 执行初始化成功了

Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.
hive>
        • Hive 2以上版本已经将Hive on MR视为废弃, 将来版本可能会移除, 现在用spark或tez结合hive的会多一些。
        • 现在企业主流使用的hive还是1.x, 部分企业逐渐向2.3版本靠拢, 3.1.2 确实还是太新了。

      2. 启动HiveServer2 (hiveserver2的服务端口默认是10000，WebUI端口默认是10002)

        $HIVE_HOME/bin/./hive --service hiveserver2
