Heng Chen commented on HBASE-16367:
-----------------------------------
is there any other race condition between HRegionServer.run and HMaster daemon
thread in constructor? I think we'd better to ensure daemon thread in the
constructor finished before we go ton HRegionServer.run, wdyt?
> 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
> Affects Versions: 1.1.2
> Reporter: Ted Yu
> Assignee: Ted Yu
> Attachments: 16367.v1.txt, 16367.v2.txt, 16367.v2.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.
