Subject [jira] [Updated] (MAPREDUCE-3829) [Gridmix] Gridmix should give better error message when input-data directory already exists and -generate option is given
Date Fri, 17 Feb 2012 05:29:59 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-3829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
