[jira] [Commented] (HBASE-12012) Improve cancellation for the scan RPCs

    [ https://issues.apache.org/jira/browse/HBASE-12012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14190385#comment-14190385 ] 

stack commented on HBASE-12012:
-------------------------------

I'm not really up on what is going on in here.  Patch looks good though.  What is the benefit?  HBASE-11564 published some numbers.  Any for this change?

Over in HBASE-11564 I asked....

bq. Should we implement http://nick-lab.gs.washington.edu/java/jdk1.5b/api/java/util/concurrent/Cancellable.html ?

.. I don't think it got a response.  When I see the new CancellableCallable interface with startCancel, makes me ask it again.

Anymore on the concern raised on tail of HBASE-11564 by [~enis]?
