Spark Sql 安装

一、启动zk、启动hdfs集群、启动hive服务(hive  --service  metastore)

二、修改spark中conf下的hive-site.xml配置文件(就和hive的client的配置文件相同)

    注:这里配置文件只需要修改一台主机就可以了,这里相当于client

三、启动spark集群

四、启动spark sql(./bin/spark-sql --master spark://node11:7077 --executor-memory 512m)

    注:配置文件spark-env.sh中如果配置的是ip 那么命令就需要用ip,如果配置文件中配置的是主机名,那么命令就要用主机名;

 

SparkSQL thrift server环境搭建

1、hive-site.xml 中添加配置

<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>

 

<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>

 

<property>

<name>hive.server2.thrift.bind.host</name>

<value>node12</value><!--  这里就是当前主机名 -->

<description>Bind host on which to run the HiveServer2 Thrift interface.Can be overridden by setting$HIVE_SERVER2_THRIFT_BIND_HOST</description>

</property>

 

二、启动spark thrift server

./sbin/start-thriftserver.sh --master spark://192.168.57.4:7077 --executor-memory 512M

三、启动以后可以通过bin目录下beeline访问

./bin/beeline

!connect  jdbc:hive2://node12:10000

注:这样可以进入sparksql控制台,但是不能查询,报错,需要将hdfs集群中core-site.xml 和 hdfs-site.xml拷贝到spark中conf下(每个spark集群节点都要拷贝)
