Hey all,
I'm attempting to decommission a node I want to remove.
First I get a status of the ring
[root@beta-new:~] #nodetool status
Datacenter: datacenter1
=======================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address Load Tokens Owns Host ID
Rack
UN 10.10.1.94 197.37 KB 256 49.4%

f2a48fc7-a362-43f5-9061-4bb3739fdeaf rack
I see that the node I want to remove is UP. Tho I believe UN means up I
don't know what it stands for.
[root@beta-new:~] #nodetool -host 10.10.1.18 decommission
Failed to connect to ' 10.10.1.18 : Connection timed out
The connection to the node I want to decommission times out. :(
I’m running this node from the seed node, and while I do see port 7199
active and listening there, I do NOT see this port active and listening on
the node that I want to decommission.
Seed node:
[root@beta-new:~] #lsof -i :7199
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 15331 root 51u IPv4 566368606 0t0 TCP *:7199 (LISTEN)
[root@beta:/etc/alternatives/cassandrahome] #lsof -i :7199
[root@beta:/etc/alternatives/cassandrahome] #
However cassandra does seem to be running on the node I want to
decommission in addition to it being shown as UN by nodetool status:
[root@beta:/etc/alternatives/cassandrahome] #netstat -tulpn | grep -i
listen | grep java

LISTEN 23039/java
tcp 0 0 0.0.0.0:7198 0.0.0.0:*
LISTEN 23039/java
So why do you think my seed is listening on port 7199 but the node I want
to get rid of is not? And how can I accomplish my goal of deleting the
unwanted node?
Thanks
Tim
