I get a strange error in Hadoop 0.18.3 (Cloudera) while I am trying to run a streaming job.
The error is: "ERROR streaming.StreamJob: Unexpected -D while processing -input|-output|-mapper|-combiner|-reducer| etc etc etc"
If I remove all -D parameters the job is accepted by Hadoop. However, I still have a warning: "WARN mapred.JobClient: Use GenericOptionsParser for parsing the arguments. Applications should implement Tool for the same."
Anybody knows what this means?
