Enis Soztutar commented on HBASE-6205:
--------------------------------------
After an offline conversation with Ted, and Jitendra, it seems that hdfs trash
works only for shell. One other concern is that trash is not exposed as hadoop
filesystem feature, so we have to use the shell-equivalent commands to
accomplish this, and it will work only on hdfs, not other file systems.
The question of whether to implement an hbase-thrash boils down to whether we
want this to work with file systems other than hdfs, and have more control on
the retention policy.

> 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 TrashCleaner 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.
