sparksql与hive整合

hive 环境启动：
./hive --service metastore & 
./hive --service hiveserver2 &


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


1.standalone模式
/spark/bin/spark-sql --master spark://spark-master:7077 --jars /spark/examples/jars/mysql-connector-java-5.1.42-bin.jar

2.yarn-client模式
/bin/spark-sql --master yarn-client --jars /spark/examples/jars/mysql-connector-java-5.1.42-bin.jar
