Subject [jira] [Commented] (HBASE-15100) Master WALProcs still never clean up
Date Wed, 13 Jan 2016 21:13:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15096990#comment-15096990
] 

Elliott Clark commented on HBASE-15100:
---------------------------------------

Looks like HBASE-14712 only caught some of the issues, but not all of them. One of our continuous
integration clusters had the masters stop coming back up. The kernel would go OOM.

We had 200k MasterWALProc's. So starting the master created TONS of tcp connections ( why
is it creating so many that it OOM's the entire kernel ? )
