Apache Sentry部署

1 环境描述

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：

o 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"?>

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   |

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

5.2.2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)

test用户可以列出所有数据库：

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

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

| database_name  |

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

| default        |

| filtered       |

| sensitive      |

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

test用户可以filtered库：
