Subject [jira] Commented: (MAPREDUCE-1217) TestMapReduceLocal fails intermittently. Assert message is unclear
Date Mon, 16 Nov 2009 19:34:39 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1217?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12778471#action_12778471
] 

Konstantin Boudnik commented on MAPREDUCE-1217:
-----------------------------------------------

The full log looks like this 
{noformat}
MultiFileWordCount failed

junit.framework.AssertionFailedError: MultiFileWordCount failed
	at org.apache.hadoop.mapreduce.TestMapReduceLocal.runMultiFileWordCount(TestMapReduceLocal.java:183)
	at org.apache.hadoop.mapreduce.TestMapReduceLocal.testWithLocal(TestMapReduceLocal.java:91)
{noformat}

The assertion message states the obvious, but doesn't help in the failure analysis.
