Subject [jira] [Commented] (PIG-3761) Outer join fail on tez
Date Tue, 11 Feb 2014 22:01:22 GMT

    [ https://issues.apache.org/jira/browse/PIG-3761?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13898377#comment-13898377

Daniel Dai commented on PIG-3761:
---------------------------------

In MR, we only use PigXXXRawComparator for sorting, not cogroup/join, that use PigWritableComparator,
which has the same null comparative logic.

> Null is not equal in terms of join. Need to change comparator to do that. e2e Join_9,
Join_10, Join_11 are manifests for this issue.
