spark-sql 指定metastore地址、读取mysql_using org.apache.spark.sql.jdbc options-优快云博客

spark-sql-hive

spark-sql --database src --hiveconf hive.metastore.uris=thrift://hdp02:2083 -e "select * from src_db2" --driver-java-options '-Djava.net.preferIPv4Stack=true'

spark-sql-jdbc

1.启动spark-sql

## --driver-class-path：指定Driver端所需jar  
## --jars ：指定executor所需要jar
spark-sql --driver-class-path /home/dw/hubg/mysql-connector-java-5.1.45-bin.jar \
--jars /home/dw/hubg/mysql-connector-java-5.1.45-bin.jar

2.执行Spark SQL语句：

spark-sql> CREATE TEMPORARY VIEW spark_mysql USING org.apache.spark.sql.jdbc OPTIONS (  url "jdbc:mysql://xxx.xx.xx.x:xxxx/shurongtest", dbtable "dmpt_serv_object",user 'root',password 'root');
