Vladimir Rodionov updated HBASE-15094:
--------------------------------------
Description:
We should add to a selection WAL files which have been copied over by different
backup sessions and which are newer than the most recent files processed for a
given table. Currently, we look for WAL files only in a files system (WALs and
OldWALs directories)
Scenario
Backup T1
Backup T2
add WAL1
Backup T1 (WAL1 becomes eligible for deletion)
- some time later
Backup T2 (WAL1 can be deleted by this time and won't get it into WAL file list
for T2)
was:We should add to a selection WAL files which have been copied over by
different backup sessions and which are newer than the most recent files
processed for a given table.
> Selection of WAL files eligible for incremental backup is broken
