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

             Summary: MasterAddressTracker & ZKNamespaceManager ZK listeners 
are missed after master recovery
                 Key: HBASE-9918
                 URL: https://issues.apache.org/jira/browse/HBASE-9918
             Project: HBase
          Issue Type: Bug
            Reporter: Jeffrey Zhong


TestZooKeeper#testRegionAssignmentAfterMasterRecoveryDueToZKExpiry always 
failed at the following verification for me in my dev env(you have to run the 
single test  not the whole TestZooKeeper suite to reproduce)
{code}
assertEquals("Number of rows should be equal to number of puts.", numberOfPuts, 
numberOfRows);
{code}

We missed two ZK listeners after master recovery MasterAddressTracker & 
ZKNamespaceManager. 

My current patch is to fix the JIRA issue while I'm wondering if we should 
totally remove the master failover implementation when ZK session expired 
because this causes reinitialize HMaster partially which is error prone and not 
a clean state to start from.
