Subject [jira] [Created] (HBASE-10544) Surface completion state of global administrative actions
Date Fri, 14 Feb 2014 23:11:19 GMT
Andrew Purtell created HBASE-10544:
--------------------------------------

             Summary: Surface completion state of global administrative actions
                 Key: HBASE-10544
                 URL: https://issues.apache.org/jira/browse/HBASE-10544
             Project: HBase
          Issue Type: Improvement
            Reporter: Andrew Purtell
             Fix For: 0.98.1, 0.99.0


When issuing requests for global administrative actions, such as major compaction, users have
to look for indirect evidence the action has completed, and cannot really be sure of the final
state. 

Hat tip to J-D and Stack.

We can approach this a couple of ways. We could add a per regionserver metric for percentage
of admin requests complete, maybe also aggregated by the master. This would provide a single
point of reference. However if we also want to insure 100% completion even in the presence
of node failures, or provide separate completion feedback for each request, I think we need
to redo flush and compaction requests as Procedures.
