Heng Chen commented on HBASE-16367: ----------------------------------- +1 > 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.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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
