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 > ------------------------------------------------- > > Key: HBASE-28806 > URL: https://issues.apache.org/jira/browse/HBASE-28806 > Project: HBase > Issue Type: Bug > Components: snapshots > Affects Versions: 2.4.14 > Reporter: mokai > Assignee: mokai > Priority: Major > Labels: pull-request-available > > 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.
