Upgrading Cassandra to 2.2

Web Services support Cassandra versions 2.2 and 1.2. If you are using Cassandra 1.2, you can maintain this version or upgrade to Cassandra 2.2.

Directly upgrading from 1.2 to 2.2 is not supported, therefore you need to upgrade your Cassandra versions in several steps. For example 1.2 > 2.0 > 2.1 > 2.2. For more information about upgrading Cassandra, see Datastax documentation.

  1. Stop all Web Services nodes.
  2. Perform Cassandra upgrade according to the Datastax.
  3. When configuring Cassandra 2.2 according to the Datastax instructions, you must enable the thrift interface. Set the the start_rpc parameter to true in the cassandra.yaml file
  4. Start all Web Services nodes.
