-----------------------------------------
Resolution: Won't Fix
> Table trash to recover table deleted by mistake
> -----------------------------------------------
>
> Key: HBASE-10535
> URL: https://issues.apache.org/jira/browse/HBASE-10535
> Project: HBase
> Issue Type: Improvement
> Reporter: Shaohui Liu
> Priority: Minor
>
> When table is deleted, only Hfiles are moved to archives dir, table and
> region infos are deleted immediately. So it's very difficult to recover
> tables which are deleted by mistakes.
> I think if we can introduce an table trash dir in HDFS. When the table is
> deleted, the entire table dir is moved to trash dir. And after an
> configurable ttl, the dir is deleted actually. This can be done by HMaster.
> If we want to recover the deleted table, we can use a tool which moves table
> dir out of trash and recovery the meta data of the table. There are many
> problems the recover tool will encountered eg, parent and daughter regions
> are all in the table dir. But I think this feature is useful to handle some
> special cases.
> Discussions are welcomed.
