huaxiang sun commented on HBASE-14644: -------------------------------------- I am debugging the same issue and know the root cause now. I am working on a patch. [~eclark], is it ok with you? Thanks Explain a little bit here: in HMaster.java, {code} protected void waitForMasterActive(){ boolean tablesOnMaster = BaseLoadBalancer.tablesOnMaster(conf); while (!(tablesOnMaster && isActiveMaster) && !isStopped() && !isAborted()) { sleeper.sleep(); } } {code} In branch-1, tablesOnMaster is false by default, so it blockes here. doMetrics() is never called. In master, tablesOnMaster is true by default so it works by default. My plan is to have a scheduleDoMetricsChore() in HRegionServer and let HMaster to override it, so HMaster can scedule a chore to call doMetrics() periodically. Please let me know if this is ok. Credit goes to [~mbertozzi] as well, I posted comments after discussion with him, thanks. > Region in transition metric is broken > ------------------------------------- > > Key: HBASE-14644 > URL: https://issues.apache.org/jira/browse/HBASE-14644 > Project: HBase > Issue Type: Bug > Reporter: Elliott Clark > Assignee: huaxiang sun > > ritCount stays 0 no matter what -- This message was sent by Atlassian JIRA (v6.3.4#6332)
