Sakthi commented on HBASE-22086:
--------------------------------
Was able to repro. Thanks for providing the steps to repro.
As list_snapshots doesn't list out any existing snapshots, nothing is written
to the quota table. But the thing is we never delete the entry from the quota
table. So I think as we always have the existing snapshots using list_snapshots
& that we rely on computing the size of the list of snapshots we list out
everytime and then re-writing it in the quota table, so it would be wise to
remove any existing snapshots entry from the quota table and have our updated
puts do the job for us.
Will work on the patch and UT. Thanks [~a00408367]. Ping [~elserj].
