[SparkSQL] hive.exec.max.dynamic.partitions配置不起作用

参考：https://issues.apache.org/jira/browse/SPARK-21574

问题描述：

动态分区插入的时候报错

Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Number of dynamic partitions created is 1483, which is more than 1000. To solve this try to set hive.exec.max.dynamic.partitions to at least 1483.

解决办法

you should use `--conf` when you start your Spark apps/shell.
