  • Apache Sentry部署

    三台hadoop集群，分别是master、slave1和slave2。下面是这三台机器的软件分布：

    • master：NameNode、ZK、HiveMetaSotre、HiveServer2、SentryServer
    • slave1：DataNode、ZK
    • slave2：DataNode、ZK

    2 软件需求

    1. MySql
    2. mysql-jdbc.jar：mysql-connector-java-5.1.38-bin.jar
    3. Hadoop
    4. Hive1.1.0：apache-hive-1.1.0-bin.tar.gz
    5. Sentry1.6.0：apache-sentry-1.6.0-incubating-bin.tar.gz 
      注意：这里的Sentry1.6.0版本对应的是Hive1.1.0版本，目前还不支持Hive1.2及以上版本。

    3 软件安装

    3.1 MySql安装

    • 在线安装：sudo apt-get install mysql-server。
    • 修改文件：vim /etc/mysql/my.cnf，内容如下：

    #bind-address           = 127.0.0.1

    bind-address            = 0.0.0.0

    • 重启mysql：service mysql restart 

    3.2 Hadoop安装

    此处省略

    3.2 Hive安装

    此处省略

    创建hive的元数据mysql数据库

    create database hive;

    CREATE USER hive IDENTIFIED BY 'hive';

    GRANT all ON hive.* TO hive@'%' IDENTIFIED BY'hive';

    flush privileges;

    3.3 Sentry安装

    1. 解压安装

    tar -zxvf apache-sentry-1.6.0-incubating-bin.tar.gz -C /opt

    2. 修改sentry的配置文件(sentry-site.xml)

    mv apache-sentry-1.6.0-incubating-bin apache-sentry-1.6.0

    cp mysql-connector-java-5.1.38-bin.jar /opt/apache-sentry-1.6.0/lib

    cd /opt/apache-sentry-1.6.0/conf

    vim sentry-site.xml

    3. 修改sentry-sitem.xml文件

    <?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>sentry.service.admin.group</name>

</property>  
<property>
<name>sentry.store.jdbc.password</name>  
<value>sentry</value>
</property>
</configuration>

    　　

    4. 配置环境变量 
    编辑vim /etc/profile

    export SENTRY_HOME=/opt/apache-sentry-1.6.0

    export PATH=${SENTRY_HOME}/bin:$PATH

    使生效source /etc/profile 
    5. 在mysql中创建sentry数据库

    create database sentry;

    CREATE USER sentry IDENTIFIED BY 'sentry';

    GRANT all ON sentry.* TO sentry@'%' IDENTIFIED BY 'sentry';

    flush privileges;

    6. 将mysql-jdbc的jar包拷贝到sentry/lib目录下

    cp mysql-connector-java-5.1.38-bin.jar  ${SENTRY_HOME}/lib

    7. 替换hadoop中jline的jar包

    rm ${HADOOP_HOME}/share/hadoop/yarn/lib/jline-0.9.94.jar

    cp ${SENTRY_HOME}/lib/jline-2.12.jar ${HADOOP_HOME}/share/hadoop/yarn/lib

    8. 初始化sentry数据库

    sentry --command schema-tool --conffile  ${SENTRY_HOME}/conf/sentry-site.xml --dbType mysql --initSchema

    9. 启动sentry服务

    sentry --command service --conffile  ${SENTRY_HOME}/conf/sentry-site.xml

    4 Hive集成Sentry

    1. 修改hive-site.xml配置文件

    <?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hive.sentry.conf.url</name>  
<value>file:///opt/apache-hive-1.1.0/conf/sentry-site.xml</value>
</property>
<!-- 配置开关控制列访问权限 -->  
<property>
<name>hive.stats.collect.scancols</name>  
<value>true</value>
</property>   
<!-- Hive Metastore集成Sentry -->  
<property>
<name>hive.metastore.pre.event.listeners</name>  
<value>org.apache.sentry.binding.metastore.MetastoreAuthzBinding</value>
</property>  
<property>
<name>hive.metastore.event.listeners</name>  
<value>org.apache.sentry.binding.metastore.SentryMetastorePostEventListener</value>
</property>  
<!-- Hive Server2集成Sentry -->  
<property>
<name>hive.server2.session.hook</name>  
<value>org.apache.sentry.binding.hive.HiveAuthzBindingSessionHook</value>
</property>  
<property>
<name>hive.security.authorization.task.factory</name>  
<value>org.apache.sentry.binding.hive.SentryHiveAuthorizationTaskFactoryImpl</value>
</property>  
<!-- 设置mysql-jdbc -->  
<property>
<name>javax.jdo.option.ConnectionURL</name>  
<value>jdbc:mysql://192.168.70.110:3306/hive?createDatabaseIfNotExist=true</value>
</property>  
<property>
<name>javax.jdo.option.ConnectionDriverName</name>  
<value>com.mysql.jdbc.Driver</value>
</property>  
<property>
<name>javax.jdo.option.ConnectionUserName</name>  
<value>hive</value>
</property>  
<property>
<name>javax.jdo.option.ConnectionPassword</name>  
<value>hive</value>
</property>
</configuration>

    　　

    2. 修改sentry-site.xml配置文件 
    注意：该文件是在hive/conf目录下的，不要和sentry/conf目录下的sentry-site.xml文件混淆！

    <?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>sentry.service.client.server.rpc-address</name>  
<value>192.168.70.110</value>
</property>  
<property>
<name>sentry.service.client.server.rpc-port</name>  
<value>8038</value>
</property>  
<property>
<name>sentry.service.client.server.rpc-connection-timeout</name>  
<value>200000</value>
</property>  
<!--配置认证-->  
<property>
<name>sentry.service.security.mode</name>  
<value>none</value>
</property>  
<property>
<name>sentry.service.server.principal</name>  
<value> </value>
</property>  
<property>
<name>sentry.service.server.keytab</name>  
<value> </value>
</property>  
<property>
<name>sentry.provider</name>  
<value>org.apache.sentry.provider.file.HadoopGroupResourceAuthorizationProvider</value>
</property>  
<property>
<name>sentry.hive.provider.backend</name>  
<value>org.apache.sentry.provider.db.SimpleDBProviderBackend</value>
</property>  
<property>
<name>sentry.metastore.service.users</name>  
<value>hive</value>  
<!--queries made by hive user (beeline) skip meta store check-->
</property>  
<property>
<name>sentry.hive.server</name>  
<value>server1</value>
</property>  
<property>
<name>sentry.hive.testing.mode</name>  
<value>true</value>
</property>
</configuration>

    　　

    3. 拷贝sentry/lib下的jar包到hive/lib目录下

    cp ${SENTRY_HOME}/lib/sentry*.jar ${HIVE_HOME}/lib

    cp ${SENTRY_HOME}/lib/shiro-*.jar ${HIVE_HOME}/lib

    注意：shiro-*.jar一定也要拷贝过去，否则会报错。 
    4. 修改Hive在HDFS上的文件权限

    hadoop fs -chown -R hive:hive /user/hive/warehouse

    hadoop fs -chmod -R 770 /user/hive/warehouse

    由于HDFS上文件是hive：hive权限，所以linux用户上能 
    5. 启动Hive Metastore服务

    hive --service metastore -hiveconf hive.root.logger=DEBUG,console

    6. 启动Hive Server2服务

    hive --service hiveserver2 -hiveconf hive.root.logger=DEBUG,console

    5 Hive权限验证

    5.1 准备测试数据

    • 创建测试数据文件：vim /tmp/events.csv，内容如下：

    10.1.2.3,US,android,createNote

    10.200.88.99,FR,windows,updateNote

    10.1.2.3,US,android,updateNote

    10.200.88.77,FR,ios,createNote

    10.1.4.5,US,windows,updateTag

    • 然后，在hive中运行下面sql语句（注意：以hive用户启动hive命令）：
    1. create database sensitive;
    2. create table sensitive.events (ip STRING, country STRING, client STRING, action STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';
    3. load data local inpath '/tmp/events.csv' overwrite into table sensitive.events;
    4. create database filtered;
    5. create view filtered.events as select country, client, action from sensitive.events;
    6. create view filtered.events_usonly as select * from filtered.events where country = 'US';
    • 在master上通过 beeline 连接 hiveserver2，运行下面命令创建角色和组：

    beeline -u "jdbc:hive2://master:10000/" -n admin -p admin -d org.apache.hive.jdbc.HiveDriver

    • 在beelin中执行下面的 sql 语句创建 role、group等：
    1. create role admin_role;
    2. GRANT ALL ON SERVER server1 TO ROLE admin_role;
    3. GRANT ROLE admin_role TO GROUP admin;
    4. create role test_role;
    5. GRANT ALL ON DATABASE filtered TO ROLE test_role;
    6. use sensitive;
    7. GRANT SELECT(ip) on TABLE sensitive.events TO ROLE test_role;
    8. GRANT ROLE test_role TO GROUP test;

    上面创建了两个角色：

    • admin_role，具有管理员权限，可以读写所有数据库，并授权给 admin 和 hive 组（对应操作系统上的组）
    • test_role，只能读写 filtered 数据库，和只能读取sensitive库中events 表中的ip字段，并授权给 test 组。

    因为系统上没有test用户和组，所以需要手动创建：useradd test

    5.2 测试

    5.2.1 测试admin_role角色

    使用admin用户访问beelin：

    beeline -u "jdbc:hive2://master:10000/" -n admin -p admin -d org.apache.hive.jdbc.HiveDriver

    admin用户属于admin_role组，具有管理员权限，可以查看所有角色：

    0: jdbc:hive2://master:10000/> show roles;

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

    |    role     |

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

    | admin_role  |

    | test_role   |

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

    5 rows selected (0.731 seconds)

    5.2.2 测试test_role角色

    使用test用户访问beeline：

    beeline -u "jdbc:hive2://master:10000/" -n test -p test -d org.apache.hive.jdbc.HiveDriver

    test用户不是管理员，是不能查看所有角色的：

    0: jdbc:hive2://master:10000/> show roles;

    ERROR : Error processing Sentry command: Access denied to test.Please grant admin privilege to test.

    Error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.SentryGrantRevokeTask. SentryAccessDeniedException: Access denied to test (state=08S01,code=1)
