hive问题： For direct MetaStore DB connections, we don't support retries at the client level

已经配置好hive，mysql作为元数据的数据库。在hive中执行drop语句出错：

drop table mytest;

错误提示如下：

FAILED: SemanticException Unable to fetch table ljz. For direct MetaStore DB connections, we don't support retries at the client level.

 我用的mysql-connctor版本是mysql-connector-java-5.1.17.jar

后来找到一个mysql-connector-java-5.1.34-bin.jar版本的， 将前者替换，重启hive后执行drop语句，竟然可以了。

神奇了。
