Ravi Gummadi updated MAPREDUCE-3829:
------------------------------------
Attachment: 3829.v0.patch
Attaching patch that fixes the issue.
With the patch, Gridmix (a) emits out an error message instead of throwing an
Exception message on to the console and (b) exits instead of failing some where
else later on.
The patch also emits out an error message in other cases like setupEmulation
fails and returns proper exit code instead of returning 0 in failure cases.
> [Gridmix] Gridmix should give better error message when input-data directory
> already exists and -generate option is given
