Subject [jira] [Commented] (CRUNCH-481) Support independent output committers for multiple outputs
Date Mon, 01 Dec 2014 12:40:13 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-481?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14229729#comment-14229729
] 

Tom White commented on CRUNCH-481:
----------------------------------

Looks good to me. With this patch, the test in CDK-756 now passes.

One question, are there cases where a job has multiple outputs to the same directory? This
is regarding CompositeOutputCommitter#commitJob, where the code path for FileOutputCommitter
is special-cased so that each path is handled only once.

> I faced this issue while trying to write to Kite and HDFS in the same pipeline. A similar
issue was logged for Kite[1][2]. 
> I was attempting to write a PCollection to Kite and a different PTable to HDFS as a text
file. The write to Kite succeeded, however the write to HDFS only produced a _SUCCESS file
with no text file.
> Commenting out the write to Kite seems to solve the issue and I can see the text file
being written.
