-------------------------------------

             Summary: NPE when IPC server ByteBuffer reservoir is turned off 
                 Key: HBASE-15114
                 URL: https://issues.apache.org/jira/browse/HBASE-15114
             Project: HBase
          Issue Type: Sub-task
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar


I was testing something else, and discovered that if we turn off the ipc out-buffer reservoir,
we are getting NPEs after HBASE-14942.
