IllegalStateException is thrown by TaskTracker
----------------------------------------------
Key: HADOOP-513
URL: http://issues.apache.org/jira/browse/HADOOP-513
Project: Hadoop
Issue Type: Bug
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.
