Hello,
Not sure if i should post this here or on Cloudera's message board,
but here goes.
When I run EC2 using the latest CDH2 and Hadoop 0.20 (by settiing the
env variables are hadoop-ec2),
and launch a job
hadoop jar ...
I get the following error
10/02/19 17:04:55 WARN mapred.JobClient: Use GenericOptionsParser for
parsing the arguments. Applications should implement Tool for the
same.

but the value of mapred.local.dir is "/mnt/hadoop/mapred/local"
Any ideas?
