             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.
