Doesn't java philosophy of `*write once and run anywhere*` apply to
hbase/hadoop?
We have deployed our production setup on Debian 7/8/9 at different points
of time.

a 3 digit
prefix based on table region range (000 - 999), would translate to
*115-0QUPHSBTLGM* with murmurhash

Agree. It solves the problem in terms of randomizing distribution, but does
not increase cardinality.

Which version of hbase are you using? Is your replication serial enabled?

You can do this several ways. I recommend you can do following way
1. Stop and remove existing replication.
2. Setup replication again and disable it temporarily
3. Export snapshot to secondary cluster.
4. Delete the table there. And restore from export snapshot
5. Enable replication.
6. You can c
if there are no references for these files
(which won't be created until snapshot is completed).
*Fix*: Increase the above configuration value to how long export snapshot
takes and then restart hmaster. Later on you can revert back.

3.0.0 should be the first release to include Backup and Restore. So far
there are no releases.

Backport is possible. We have backported to 2.1.x and using it.
Waiting for some PRs to merge so that I can put some effort in getting the
backport available for active 2.x releases.
