Hi,

 

In Hadoop, while creating Table in hive i am getting stuck in below error

 

15/04/21 12:35:34 INFO log.PerfLogger: <PERFLOG method=Driver.run from=org.apache.hadoop.hive.ql.Driver>
15/04/21 12:35:34 INFO log.PerfLogger: <PERFLOG method=TimeToSubmit from=org.apache.hadoop.hive.ql.Driver>

15/04/21 12:35:34 DEBUG lockmgr.DummyTxnManager: Adding database:mkt_incoming to list of lock outputs


After restart the zookeeper service i am able to successfully run the query,

But after some time again facing the same issue/error, I am stuck on the same error.

 

is there any solution to overcome this issue, or any tuning i can do for resolve this issue.

 

Please suggest on this.

This seems similar to this problems of ZooKeeper leaks with HiveServer2
https://issues.apache.org/jira/browse/HIVE-9119

Hue is also not closing the Hive queries, so you could try to bump the
number of connections/clients in CM?
