>    Affects Versions: 1.1.2
>            Reporter: 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.
> 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.
