> 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.
