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。
