Subject [jira] Commented: (HADOOP-3267) Counters value of reduce input records do not match map output records
Date Fri, 07 Nov 2008 20:55:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12645879#action_12645879
] 

Jean-Daniel Cryans commented on HADOOP-3267:
--------------------------------------------

We just had the same problem using 0.18.1 where some counters would return double their value
in a unit test. I tried the first part of the patch and it fixed the problem. I was about
to refresh it so that it applies to trunk and I ran the test without the fix but it didn't
fail as expected. I then tried branch 0.19 with our test and we didn't see the problem so
it seem to be fixed for versions > 0.18.

I suggest closing this issue.
