Registered listeners not getting removed leading to memory leak in HBaseAdmin
-----------------------------------------------------------------------------

                 Key: HBASE-5073
                 URL: https://issues.apache.org/jira/browse/HBASE-5073
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.90.4
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan
             Fix For: 0.90.5


HBaseAdmin apis like tableExists(), flush, split, closeRegion uses catalog 
tracker.  Every time Root node tracker and meta node tracker are started and a 
listener is registered.  But after the operations are performed the listeners 
are not getting removed. Hence if the admin apis are consistently used then it 
may lead to memory leak.
