Subject [jira] [Commented] (HBASE-4518) TestServerCustomProtocol is flaky
Date Wed, 02 Nov 2011 17:05:32 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4518?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13142307#comment-13142307
] 

Gary Helmling commented on HBASE-4518:
--------------------------------------

@Stack,

Yes, for some reason in the original code I was being a bit too "clever" and registering the
protocol handler directly.  Maybe it was before all the connecting bits had been filled in
yet...  In any case, the manual registration in the original code would mean that the PingHandler
would not get re-registered if a region closed on one RS and was reopened on another.  So
that is a flaw.  And the test code should really be doing what we tell people to do with endpoints,
which is to configure them as coprocessors.
