sparksql与hive整合

hive配置

编辑 $HIVE_HOME/conf/hive-site.xml,增加如下内容:

<property>
  <name>hive.metastore.uris</name>
  <value>thrift://master:9083</value>
  <description>Thrift uri for the remote metastore. Used by metastore client to connect to remote metastore.</description>
</property>

启动hive metastore

 启动 metastore:
 $hive --service metastore &
 查看 metastore:
 $jobs
[1]+  Running                 hive --service metastore &

关闭 metastore:

$kill %1

kill %jobid,1代表job id

spark配置

将 $HIVE_HOME/conf/hive-site.xml copy或者软链 到 $SPARK_HOME/conf/
将 $HIVE_HOME/lib/mysql-connector-java-5.1.12.jar copy或者软链到$SPARK_HOME/lib/
copy或者软链$SPARK_HOME/lib/ 是方便spark standalone模式使用

启动spark-sql

  1. standalone模式

    ./bin/spark-sql --master spark:master:7077 --jars /home/stark_summer/spark/spark-1.4/spark-1.4.1/lib/mysql-connector-java-5.1.12.jar
  2. yarn-client模式
$./bin/spark-sql --master yarn-client --jars /home/stark_summer/spark/spark-1.4/spark-1.4.1/lib/mysql-connector-java-5.1.12.jar

执行 sql:
select count(*) from o2o_app;

结果:
302
