---------------------------------------
Key: MAPREDUCE-1911
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1911
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: contrib/streaming
Reporter: Amareshwari Sriramadasu
Fix For: 0.22.0
Here are some of the findings by Karam while verifying -info option in
streaming:
# We need to add "Optional" for -mapper, -reducer,-combiner and -file options.
# For -inputformat and -outputformat options, we should put "Optional" in the
prefix for the sake on uniformity.
# We need to remove -cluster decription.
# -help option is not displayed in usage message.
# when displaying message for -info or -help options, we should not display
"Streaming Job Failed!"; also exit code should be 0 in case of -help/-info
option.
