> Key: HBASE-29146
> URL: https://issues.apache.org/jira/browse/HBASE-29146
> Project: HBase
> Issue Type: Bug
> Components: backup&restore
> Reporter: Hernan Gelaf-Romer
> Assignee: Hernan Gelaf-Romer
> Priority: Major
> Labels: pull-request-available
>
> 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
