> 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.
