Szabolcs Bukros commented on HBASE-26707:
-----------------------------------------

During implementation I have found an issue with 
bulkLoadListener.failedBulkLoad at 
[https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java#L7320]

The passed param is the staged path, but the method expects the file's original 
location. This could lead to leaving the hfile in the staging dir after failing 
a bulkload and because cleanup deletes staging loosing the hfile.

This is also fixed in the attached PR.

> Make sure we only do a single rename operation during bulkload when 
> StoreEngine does not require the the use of tmp directories.
