Finding whether a new node is successfully added or not
Dear all, I added a new node to my 1 node Cassandra cluster. Now I want to find out whether it is added successfully or not. Also do I need to restart the already running node after entering the seed value. Please help me.

Re: Finding whether a new node is successfully added or not
Hi there, You can check the ring info with nodetool. Furthermore you can take a look at the streaming statistics: lots of pending indicates a node that is still receiving data from it's seed(s). As far as I'm aware of the seed value will be read upon start: so a restart is required. Good luck. 2012/6/4 Prakrati Agrawal prakrati.agra...@mu-sigma.com Dear all, ** ** I added a new node to my 1 node Cassandra cluster. Now I want to find out whether it is added successfully or not.

Hi Prakrati, bin/nodetool -host ip ring Refer here at Cassandra wiki http://wiki.apache.org/cassandra/NodeTool for more details. A restart is needed as I know as node need to communicate with the seeds and make sense of the cluster it is in.
