Subject [jira] [Commented] (MAPREDUCE-3462) Job submission failing in JUnit tests
Date Mon, 26 Dec 2011 09:03:30 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3462?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13175915#comment-13175915
] 

Ravi Prakash commented on MAPREDUCE-3462:
-----------------------------------------

I'd be wary of adding it in src/main/..mapred-default.xml . I'd think src/test/../mapred-test.xml
is where it should be added if at all. If that doesn't work currently, we should make it work.
Just out of curiosity, do you know of any other tests which are failing due to this exception?
