stack commented on HBASE-8803:
------------------------------
This is an excellent improvement. There is the issue above that needs looking
into where we seemingly do not restore node to its former state. Should also
redo these scripts as pure java since they are critical functionality now but
that could be done in another issue. Reading elsewhere [~jmspaggi] is resource
constrained which probably explains why no progress here.
> region_mover.rb should move multiple regions at a time
