基于sparksql调用shell脚本运行SQL

基于sparksql调用shell脚本运行SQL，sparksql提供了类似hive中的 -e  , -f ,-i的选项

1、定时调用脚本

#!/bin/sh  
# upload logs to hdfs

--conf spark.ui.port=4075 

默觉得4040，会与其它正在跑的任务冲突，这里改动为4075

设定任务使用的内存与CPU资源

--executor-memory 6g --total-executor-cores 45

原来的语句是用hive -e 运行的，改动为spark后速度大加快了。

原来为15min，提升速度后为 45s.
