Brandon Williams commented on CASSANDRA-4162:
---------------------------------------------

bq. I want a reliable way to remove a node from the cluster and disable traffic 
to it

Restarting with -Dcassandra.join_ring=false will do that.

>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.0.9
>         Environment: reported on IRC, believe it was a linux environment, 
> nick "rhone", cassandra 1.0.8

>            Priority: Minor

> This ticket derives from #cassandra, aaron_morton and I assisted a user who 
> had run "disablethrift" and "disablegossip" and was confused as to why he was 
> seeing writes to his node.
> Aaron and I went through a series of debugging questions, user verified that 
> there was traffic on the gossip port. His node was showing as down from the 
> perspective of other nodes, and nodetool also showed that gossip was not 
> active.
> Aaron read the code and had the user turn debug logging on. The user saw 
> Hinted Handoff messages being delivered and Aaron confirmed in the code that 
> a hinted handoff delivery session only checks gossip state when it first 
> starts. As a result, it will continue to deliver hints and disregard gossip 
> state on the target node.
> per nodetool docs
> "
> disablegossip          - Disable gossip (effectively marking the node dead)
> "
> I believe most people will be using disablegossip and disablethrift for 
> operational reasons, and propose that they do not expect HH delivery to 
> continue, via gossip, when they have run "disablegossip".
