Subject Re: Hiveserver2 memory / thread leak v 0.13.1 (hdp-2.1.5)
Date Fri, 06 Feb 2015 09:48:45 GMT
Alexander,

Can you share the jmap histo (or even better, a heapdump)? What are the top consumers? What
are the  heap+permgen sizes that the JVM is configured to use?

FYI, we fixed this memory leak in Hive-14: https://issues.apache.org/jira/browse/HIVE-7353.

Thanks,
-Vaibhav

Subject: Hiveserver2 memory / thread leak v 0.13.1 (hdp-2.1.5)

I'm using hive-0.13.1 (hdp-2.1.5)

Hiveserver2 is running for 6 days

nobody is connected to the server now.
last connection was 30 min ago.

Used memory: 688MB   (after GC)
Live threads: 297
perm: 99.6% used

Two days ago numbers were
Used memory: 259MB   (after GC)
Live threads: 108
perm: 98% used

Looks like a memory/thread leak.

Today and 2 days ago VisualVM screenshots are attached
