    Resolution: Duplicate

Thanks for the script Ophir. I'm marking this as DUP of HBASE-5504. I linked back to this
issue from there.

> A region deletion tool can be very useful to remove large amount of data.
> For example, it can be used to remove all data older than specific date (assuming your
data sorted by dates) etc...
> This tool should be something as follows:
> Input: region key or (even better!) start & end key.
> 1. Split region to isolate the keys.
> 2. Disable the relevant regions.
> 3. Delete files from the file system.
> 4. Update .META. table.
