Subject [jira] [Commented] (HBASE-10509) TestRowProcessorEndpoint fails with missing required field row_processor_result
Date Wed, 12 Feb 2014 21:50:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13899623#comment-13899623
] 

Andrew Purtell commented on HBASE-10509:
----------------------------------------

The protobuf do() function would get a null for the failure case prior to this change. Now
we always send through an object built with the required field set. Only shows up when using
the IBM JDK so I am assuming some difference in use of reflection in protobuf (?). I was not
feeling well so stopped investigation after finding a workaround. We could dig deeper in lieu
of this patch but I don't know what other change we could make under our control.
