Subject [jira] [Commented] (CRUNCH-163) Union ignores input branches
Date Wed, 06 Feb 2013 13:05:17 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13572386#comment-13572386

Gabriel Reid commented on CRUNCH-163:
-------------------------------------

Thanks for the tests Tim.

I noticed that the package names for Crunch are the old com.cloudera.* package names -- it
looks like these were built with an old version of Crunch.

In any case, that doesn't take away from this being an issue. On the current trunk, singleUnionOfTwoReads
and doubleUnionWithMaterialize both fail, the others pass. The failing test for singleUnionOfTwoReads
is pretty easy to resolve, but the other one looks like it'll take more effort, so I'll try
to have a look at it later this evening.
