Number of dynamic partitions exceeded hive.exec.max.dynamic.partitions.pernode

动态分区数太大的问题：[Fatal Error] Operator FS_2 (id=2): Number of dynamic partitions exceeded hive.exec.max.dynamic.partitions.pernode.

查看最大分区数：

hive> set hive.exec.max.dynamic.partitions.pernode;

hive.exec.max.dynamic.partitions.pernode=100

将该參数设置的大一点，问题即解决。
