restart cassandra after instances stop/start

2011-06-05 Thread Khanh Nguyen
Hi,

I followed the instructions here
http://nubetech.co/setting-up-cassandra-clusters-in-the-cloud-with-whirr
to set up an ec2 cluster on AWS. Everything works great until I stop
my instances (to save money) and restart them because the instances
get new IPs. What changes do I need to make in order to get my
cassandra cluster up and running again? Thanks.

Regards,

I see..

What if I only need to resume the cluster and don't worry about any
data? Each time I use whirr to set up a new clusters, new EBS volumes
are also created and I got charged for the volumes at full month rate
even though I only use them for a few hours.Thanks.

 Hi,

 There is no easy way to suspend a cluster started with Whirr without
 loosing all the data stored on the nodes. You need a custom tool to
 export and save data on shutdown (maybe to S3) and load it back when
 you start the cluster again.

 We are tracking progress on this issue here:
 https://issues.apache.org/jira/browse/WHIRR-309
