在创建好一个分区表后，执行动态分区插入数据，抛出了错误：

Caused by: org.apache.hadoop.hive.ql.metadata.HiveFatalException: [Error 20004]: Fatal error occurred when node tried to create too many dynamic partitions. The maximum number of dynamic partitions is controlled by

解决方案：

在执行插入数据到分区时，添加参数设置：

set hive.exec.dynamic.partition=true;
set hive.exec.dynamic.partition.mode=nonstrict;
set hive.exec.max.dynamic.partitions.pernode=10000;
set hive.exec.max.dynamic.partitions=10000;
set hive.exec.max.created.files=10000;
