Subject [jira] [Commented] (HBASE-12581) TestCellACLWithMultipleVersions failing since task 5 HBASE-12404 (HBASE-12404 addendum)
Date Sun, 30 Nov 2014 22:15:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14229259#comment-14229259
] 

Andrew Purtell commented on HBASE-12581:
----------------------------------------

It's also expected, by current design, that operations in flight concurrent with a grant may
be strictly speaking improperly denied during the period when notification of the grant is
propagating across the cluster. (And operations in flight concurrent with a revoke may still
succeed until notice of revocation has propagated.) We are using ZK watchers and znode updates
as a notification mechanism, so changes do take effect, and "quickly". However, this can be
improved. We have had several proposals on other JIRAs (HBASE-5487, HBASE-7254, HBASE-9864,
etc) to change grant and revoke implementation to be Procedure based, which could insure application
at all nodes succeeded prior to returning a success indication to the client.

> TestCellACLWithMultipleVersions failed after HBASE-12404 went in (though it passed twice
on hadoopqa!).  Fails locally too.  Here, make a Connection when we go to check perms.  That
seems to fix it. Going to commit since patch is just more of hbase-12404... this is in essence
and addendum.
