Hello,
I'm using 0.19.2-dev-core (checked out from cvs and build). With 51 maps, i
have a case where 50 tasks have completed and 1 is pending, about 1400
records left for this one to process. The completed map taska have written
out 18GB to the HDFS.
The last map task is forrever in the pending queue - is this is issue my
setup/config or do others have the problem?

Thank you
