Subject [jira] [Updated] (HBASE-12665) When aborting, dump metrics
Date Wed, 10 Dec 2014 05:26:13 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12665?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-12665:
--------------------------
       Resolution: Fixed
    Fix Version/s:     (was: 0.98.9)
     Release Note: When regionserver aborts, we dump subset of metrics into the log (We used
to do this too pre-0.96 but was lost when we refactored metrics)
     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

Committed to branch-1+  Can't do this in 0.98 because relies on JMXJsonServlet which is in
hadoop in 0.98 (we pull httpserver into hbase from hadoop in branch-1+)

> We used to dump out all metrics when we were exiting on abort. Was of use debugging why
the abort.  We used to have this.  [~jdcryans] noticed it was dropped by his brother [~eclark]
over in HBASE-6410 "Move RegionServer Metrics to metrics2" To stop the two brothers fighting
I intervened with this patch.
