> 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.
