-----------------------------------------

Which version of hadoop are you using ? Is it having the patch of MAPREDUCE-1979 already ?

> Gridmix always throws an FileAlreadyExistsException even ouput directory is not available
in HDFS. Actually I was launching the Gridmix in a command line for generating the data, before
launching I just make sure the output directory is not available in the HDFS by deleting the
folder if already exists.However, I could see output directory already exists exception every
time. Please see the attached logs for more information.
