Spark Thrift Server
ThriftServer是一个JDBC/ODBC接口,用户可以通过JDBC/ODBC连接ThriftServer来访问SparkSQL的数据。ThriftServer在启动的时候,会启动了一个SparkSQL的应用程序,而通过JDBC/ODBC连接进来的客户端共同分享这个SparkSQL应用程序的资源,也就是说不同的用户之间可以共享数据;ThriftServer启动时还开启一个侦听器,等待JDBC客户端的连接和提交查询。所以,在配置ThriftServer的时候,至少要配置ThriftServer的主机名和端口,如果要使用Hive数据的话,还要提供Hive Metastore的uris。
具体配置
1、修改$SPARK_HOME/conf目录下的hive-site.xml文件,具体配置如下
<?xml version="1.0"?> <configuration> <!-- Hive Metastore 配置 --> <property> <name>hive.metastore.uris</name> <value>thrift://m1:9083</value> <description>Thrift URI for the remote metastore. Used by metastore client to connect to remote metastore.</description> </property> <property> <name>hive.server2.thrift.min.worker.threads</name> <value>5</value> <description>Minimum number of Thrift worker threads</description> </property> <property> <name>hive.server2.thrift.max.worker.threads</name> <value>500</value> <description>Maximum number of Thrift worker threads</description> </property> <!-- Thrift Server服务器绑定的端口 --> <property> <name>hive.server2.thrift.port</name> <value>10000</value> <description>Port number of HiveServer2 Thrift interface. Can be overridden by setting $HIVE_SERVER2_THRIFT_PORT</description> </property> <!-- Thrift Server服务器地址 --> <property> <name>hive.server2.thrift.bind.host</name> <value>m1</value> <description>Bind host on which to run the HiveServer2 Thrift interface.Can be overridden by setting$HIVE_SERVER2_THRIFT_BIND_HOST</description> </property> </configuration>
2、启动hive metastore
$nohup hive --service metastore > metastore.log 2>&1 &
3、启动spark
./sbin/start-all.sh
4、启动Thrift Server
./sbin/start-thriftserver.sh --master spark://m1:7077
5、客户端连接Thrift Server
启动beeline
./bin/beeline
连接服务
!connect jdbc:hive2://m1:10000
连接成功后就可以在这里使用HQL进行操作了
