     [ https://issues.apache.org/jira/browse/HBASE-9330?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jean-Daniel Cryans updated HBASE-9330:
--------------------------------------

    Attachment: HBASE-9330.patch

Here's a patch that fixes it. On my cluster I go from about 4k threads to only 600. I don't like the patch so much though.
