If you  set offheap_buffers in cassandra.yaml in 3.0.10, you'll get exception 
offheap_buffers are not available in 3.0. They will be re-introduced in a future release, see https://issues.apache.org/jira/browse/CASSANDRA-9472 for details
on Cassandra start.

Thank you.  My question was about a different option named "offheap_objects".  I've already figured out that it was removed even earlier with the release of 3.0.
