解决方案:
将hive-site.xml中的



datanucleus.connectionPoolingType
Hikari

Expects one of [bonecp, dbcp, hikaricp, none].
Specify connection pool library for datanucleus



修改为



datanucleus.connectionPoolingType
dbcp

Expects one of [bonecp, dbcp, hikaricp, none].
Specify connection pool library for datanucleus



即可。
注意:hive和spark中都要修改。
