Ted Yu created HBASE-16367: ------------------------------ Summary: 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 Reporter: Ted Yu Assignee: 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. {code} this.oldLogDir = createInitialFileSystemLayout(); HFileSystem.addLocationsOrderInterceptor(conf); LOG.info("creating splitLogManager"); {code} 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)
