Devaraj K commented on MAPREDUCE-2309:
--------------------------------------
In version 0.20.2, using the command "hadoop job -list-attempt-ids"
{code:xml}
linux124:/home/devaraj/hadoop/bin # ./hadoop job -list-attempt-ids
job_201102101059_0008 type state
linux124:/home/devaraj/hadoop/bin #
{code}
If we give the state other than "pending", "running", "completed", "failed",
"killed" or task type other than "map", "reduce", "setup", "cleanup" it is
simply returning to the shell.
In version 0.23 snapshot, using the command "mapred job -list-attempt-ids"
{code:xml}
inux124:/home/devaraj/hadoop_latest/hadoop-mapred-0.23.0-SNAPSHOT/bin #
./mapred job -list-attempt-ids job_201102101036_0002 type state

It is throwing the above exception if we give invalid task type.
Instead we can display some message like "Unsupported task state." or
"Unsupported task type."
