[jira] [Resolved] (HBASE-11887) Memory retention in branch-1; millions of instances of LiteralByteString for column qualifier and value

["stack (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-11887?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-11887.
---------------------------
       Resolution: Fixed
    Fix Version/s: 0.98.8
     Hadoop Flags: Reviewed

Applied to 0.98+. 0.98 doesn't seem to need it but going by what it does in branch-1, probably no harm letting go of these references so they get cleaned up early and maybe less-likely promoted (hope that ok [~apurtell])

> Trying to test branch-1, I run out of mem pretty fast.  Looking at dumps, I see too many instances of LiteralByteString.  Seem to be 'qualifiers' and 'values' out of pb QualifierValue... and on up to the multi call into the server. Am having trouble finding how the retention is being done... Filing issue in meantime while work on it.
