Hi All, I am looking into the possibility of upgrading from Cassandra 1.2.14 to Cassandra 2.1 in the following manor.
I have a large Cassandra cluster with dozens of nodes, and would like to build new instances at version 2.1 to join the cluster and once they have successfully joined the rink these should then stream data in. Once they have fully joined the cluster I would like to decommission a single Cassandra 1.2.14 instance, and repeat. Due to the fact that our 2.1 installations have a different directory layout we would like to go with this ‘streaming’ option for the upgrade rather than an inplace upgrade. Does anyone foresee any issues with this. Thanks in advance.
