Subject [jira] Commented: (PIG-926) Merge-Join phase 2
Date Thu, 20 Aug 2009 17:28:14 GMT

    [ https://issues.apache.org/jira/browse/PIG-926?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745510#action_12745510
] 

Ashutosh Chauhan commented on PIG-926:
--------------------------------------

Findbugs warning is about dummyTuple. A dummyTuple is used as an argument to call appropriate
overloaded getNext() of physical operator. Since this is just a marker, it is initialized
as null and never updated. Findbugs thinks that it will always be null, which is true, but
it doesn't affect in any way. There is no workaround to get rid of this warning.
