Hi,
We had a cassandra cluster(DSE 2.1.1-1) with few nodes. We want to restore the data into new cassandra cluster(DSE 2.2.1).
The steps we followed below,
1. Took a snapshot from one of the node in existing cluster.
2. Brought up a new cluster with DSE 2.2.1
3. Just created a keyspace in the new cluster.
4. copied all the files from <snapshot>/<timestamp> to /var/lib/cassandra/data/<keyspace>/
5. started the cassandra service by using (dse cassandra)
But cant retrieve the data through cassandra-cli
We tried another option also.
1. Created keyspace and column families in the new cassandra cluster
2. restored the snapshot
This also not working.
The links we followed,
http://www.datastax.com/docs/1.1/operations/backup_restore
http://jonathanhui.com/cassandra-data-maintenance-backup-and-system-recovery
Is there anything we missed?
Thanks in advance.
