> Key: HBASE-29239
> URL: https://issues.apache.org/jira/browse/HBASE-29239
> Project: HBase
> Issue Type: Bug
> Components: backup&restore
> Reporter: Hernan Gelaf-Romer
> Assignee: Hernan Gelaf-Romer
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0-alpha-1, 2.7.0, 3.0.0-beta-2, 2.6.3
>
>
> Recently, I've discovered that it's possible to break backups if the
> MapReduceHFileSplitterJob fail to run successfully.
>
> The MR job first populates the target directory, but fails at some other
> point. When re-tried, the MR fails because the target directory already
> exists. We should clean up the target bulkload directory if the HFileSplitter
> job fails for any reason to avoid this failure mode
