Hive metastore leaking memory?

Hive metastore leaking memory?

Expert Contributor

hdp 2.6.0, HMS has 6GB memory, the metastore itself is mysql.

After a few days the server hosting the HMS will have its CPU 100% used, hive queries are slow, and looking at the GC logs the HMS is constantly having stop the world events. Restarting the metastore 'fixes' the problem for a few days.

I have found a few JIRA link related to memory leaks https://issues.apache.org/jira/browse/HIVE-15551 or https://issues.apache.org/jira/browse/HIVE-13749 .

Is it a known issue in hdp 2.6.0? Is it known if the latest hdp version is fixed?

Thanks,
