Amar Kamat commented on MAPREDUCE-3829:
---------------------------------------
Ravi,
Should we reuse the 'STARTUP_FAILED_ERROR' in DistributedCacheEmulator? LOG
statements should point to the real cause of the error. Lets try to keep all
the error codes in one place i.e Gridmix.java. Other changes looks good to me.
> [Gridmix] Gridmix should give better error message when input-data directory
> already exists and -generate option is given
