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)
