             Summary: Cleanup stoppable/abortable/closeable in the online snapshot cases.
                 Key: HBASE-7461
                 URL: https://issues.apache.org/jira/browse/HBASE-7461
             Project: HBase
          Issue Type: Sub-task
            Reporter: Jonathan Hsieh


The RegionServer managers implement abort, close, and stop -- although the interfaces are similar and all their meanings are muddled.

The conventions in hbase are gernally: 
abort == passed into managers so they can trigger a suicide kill (for rs or hmaster)
stop == *managers for on the way to cleanup
cancel == operations that don't kill long running processes but bail out of the current attempt.
close == files or network resources.

This patch brings the naming into line.
