chunhui shen updated HBASE-6205:
--------------------------------
Description:
User may drop table accidentally because of error code or other uncertain
reasons.
Unfortunately, it happens in our environment because one user make a mistake
between production cluster and testing cluster.
So, I just give a suggestion, do we need to support an option to keep data of
dropped table for some time, e.g. 1 day
In the patch:
We make a new dir named .trashtables in the rood dir.
In the DeleteTableHandler, we move files in dropped table's dir to trash table
dir instead of deleting them directly.
And Create new class TrashTableCleaner which will clean dropped tables if it is
time out with a period check.
Default keep time for dropped tables is 1 day, and check period is 1 hour.
