Hi, I'm running a 4 nodes Cassandra cluster, and I'm facing the same
problem (node not present on nodetool ring, but unreachable on CLI describe
cluster...). I'm currently running version 1.0.2, but I have update from
0.8.x, the problem may exist since a while, I don't really know. I can't
stop my cluster, but I don't know how to apply the patch to repair the
consequences of this bug by removing definitely this node.

Can someone tell me the way to proceed to apply a patch and call this java
function ?

Thank you,

Alain

If you're not already familiar with building cassandra, the easiest
thing to do is wait for 1.0.6 (I just committed this patch) and then
call it via jconsole.

By the way, nice comment on the patch "// do not pass go, do not collect
200 dollars, just gtfo", it looks like you have some fun while developping
Cassandra @Datastax ;)
