Jeffrey Zhong created HBASE-9918:
------------------------------------
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.
