NPE in UUIDGen.decompose - Cassandra 1.2.9

[Elias Ross <ge...@noderunner.net>]

Here's an error I've seen when adding while decommissioning a different node.

I didn't see anything in JIRA about the same issue, but there are
similar issues.

Has this been fixed? Is this a new bug? This is Cassandra 1.2.9.

Thank you.

Dunno, though as you say there are Decommission improvements upstream in
2.x.

If I were you, and could repro this, I would :

1) file a JIRA with repro steps
2) upgrade to 1.2.18
3) see if I could still repro
