Subject Re: Is to ok restart DECOMMISION
Date Fri, 16 Sep 2016 01:18:16 GMT
I've done that several times. Kill the process, restart it, let it
sync, decommission.

You'll need enough space on the receiving nodes for the full set of
data, on top of the other data that was already sent earlier, plus
room to cleanup/compact it.

Before you kill, check system.log to see if it died on anything. If
so, the decommission process will never finish. If not, let it
continue. Of particular note is that by default transferring large
sstables will timeout. You can fix that by adjusting
streaming_socket_timeout_in_ms to a sufficiently large value (I set it
to a day).
