Sameer Paranjpye updated HADOOP-513:
------------------------------------
Component/s: mapred
> IllegalStateException is thrown by TaskTracker
> ----------------------------------------------
>
> Key: HADOOP-513
> URL: http://issues.apache.org/jira/browse/HADOOP-513
> Project: Hadoop
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.5.0
> Reporter: Konstantin Shvachko
>
> I am running TestDFSIO on a one node cluster and getting
> IllegalStateException for each map task run as listed below.
> The same exceptions are flooding logs for TestMiniMRWithDFS on my nightly
> build for quite a while now.
> Does anybody know what that is?
> My understanding is that if it is "illegal", then tests should fail.
> If not then it should be caught and ignored INTERNALLY.
