Is there a way to get rid of stale information that shows up for removed/dead nodes in gossip, without a complete cluster bounce?

unsafeAssassinate remove gossip info and token range ownership for a node
WITHOUT streaming data.

It no longer shows up, but I will definitely investigate that option. What exactly does it do?

Rahul,
If the removed node is still showing up in gossip state, you can remove it
with 'unsafeAssassinate' via a JMX tool such as jconsole or jmxterm.

After removing a node, it's information can persist in the Gossiper for up
to 3 days, after which time it should be removed.
Are you having issues with a removed node state persisting for longer?
