> At the moment, if a bulkload file is archived as we're backing it up, or if there are archive files that need to be loaded, we run into the following exception
>  
> ```
> Unexpected Exception : org.apache.hadoop.mapred.FileAlreadyExistsException
> ```
>  
> The happens because we're running MR jobs to re-split these HFiles, and we cannot run subsequent MR jobs against the same target bulk output directory without first cleaning that directory up. We should make sure we properly clean up the bulkload output directory in between runs of MapReduceHFileSplitterJob
