Aborting a decommission

[Timothy Palpant <ti...@palpant.us>]

Hi!

I was wondering if it is possible to abort/cancel a decommission that was
initiated with `nodetool decommission`.

The use case I am interested in is being able to stop a decommission that
is in progress (returning the host to UN state) so that I can deal with
another DN node first, without performing two token ring changes at the
same time.

Relatedly, does the reassignment of token ranges during a decommission
happen at the start of the decommission, or at the end (after all data has
been streamed to the new node)?

Thanks!
Tim

Tim, you can restart a node in decommission mode, after that, I will start
as a normal node. But it will be nice to have a tool to do that.
