------------------------------
Summary: Race between master and region server initialization may
lead to premature server abort
Key: HBASE-16367
URL: https://issues.apache.org/jira/browse/HBASE-16367
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
I was troubleshooting a case where hbase (1.1.2) master always dies shortly
after start - see attached master log snippet.
It turned out that master initialization thread was racing with
HRegionServer#preRegistrationInitialization() (initializeZooKeeper, actually)
since HMaster extends HRegionServer.
{code}
this.oldLogDir = createInitialFileSystemLayout();
HFileSystem.addLocationsOrderInterceptor(conf);
LOG.info("creating splitLogManager");
{code}
Execution didn't reach the last log line before region server declared cluster
Id being null.
