mokai commented on HBASE-28806:
-------------------------------
Snapshot with merged regions has no parent region info, but keeps parent region
of split. Export snapshot will copy the hfiles of parent region 1~3 times. If
the same hfile handing by different mappers parallelly, it causes task fail.
> ExportSnapshot failed if reference file presented

> Project: HBase

> ExportSnapshot tasks failed due to FNFE.
> If there are reference files in data.manifest, they are converted to referred
> files, so same referred files are handled in multi map tasks. It will cause
> FNFE if the same file copied in different map tasks concurrently.
