> Key: HBASE-16367
> URL: https://issues.apache.org/jira/browse/HBASE-16367
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.1.2
> Reporter: Ted Yu
> Assignee: Ted Yu
> Fix For: 2.0.0, 1.4.0
>
> Attachments: 16367.addendum, 16367.v1.txt, 16367.v2.txt,

> 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.
> Through additional logging in master:
> {code}
> this.oldLogDir = createInitialFileSystemLayout();
> HFileSystem.addLocationsOrderInterceptor(conf);
> LOG.info("creating splitLogManager");
> {code}
> I found that execution didn't reach the last log line before region server
> declared cluster Id being null.
