Josh Elser commented on HBASE-17852:
------------------------------------
bq. Yeah, as I recall, Vlad ran into a case where, when trying to make sure
that we didn't lose files in incremental backups, we grabbed a table-level
lock. Because this lock was on the hbase:backup table, it introduced a
situation where the system deadlocked. By introducing a table which is
explicitly tracking the bulk-loaded files, it avoids this deadlock scenario.
[~vrodionov], when you have a moment, could you please describe this problem
you ran into for us and the pros/cons on you chose a separate table as the way
to work around it?
