[BZ 1567251] Disable auto snapshots and env var for taking snapshots #410

Closed jsanda closed 6 years ago

jsanda commented 6 years ago

Disabling auto snapshots for Cassandra by default because 1) we do not have a mechanism for snapshots and because 2) the temp data temp tables introduced in OpenShift 3.7 generate a lot of snapshots that can eat up disk space in a hurry.

This commit introduces a new environment variable, TAKE_SNAPSHOT, which if set to "true" will cause a snapshot to be generated in the cassandra-poststart.sh script which is run from the postStart lifecycle hook. The snapshop name uses a default value of a timestamp.
