> Project: Hadoop
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.13.0
> Reporter: Nigel Daley
> Assignee: Arun C Murthy
> Attachments: HADOOP-1332_1_20070529.patch

>
> Since April 22 I've been seeing sporadic failures of these tests on Windows:
> - TestMiniMRClasspath
> - TestMiniMRLocalFS
> - TestMiniMRDFSCaching
> The change log since then can be viewed starting at build 66:
> http://lucene.zones.apache.org:8080/hudson/job/Hadoop-Nightly/66/
> The tests fail because they timeout.
> They timeout because one of the task trackers doesn't go idle.
> One of the task trackers doesn't go idle because a map fails and has to be
> killed.
> Reordered and annotated tests logs (my comments are in parenthesis):
> (map 0 executes and logs a 'done' and two 'completed' messages):
