Dear Guys,

 

Thank you so much for your reply.

 

Currently I have two Cassandra nodes running in ring.  I have installed Cassandra on following location;

 

/root/apache-cassandra-0.8.1

 

Now my questions are;

 

1.       How we upgrade (Step by Step version like 0.8.1 to 0.8.5, then 0.8.5 to 1.0.0……….to 1.1.0)

2.       Once I take snapshot, is it have full data or only one node data?

3.       Once I download apache-cassandra-0.8.5-bin.tar.gz then after untar, What Can I do? I only move few folder from previous version directory to new version directory or move all directories and files.

4.       After moving data is there any command required ?

 

 

Thanks & Regards
