>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 1.1.2
>            Reporter: Ted Yu
>            Assignee: Ted Yu
>         Attachments: 16367.v1.txt, 16367.v2.txt, 16367.v3.txt, 63908-master.log

>
> 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.
