Hello,
Today we tried to setup DataStaxOpsCenter-5.2.2.2015102711-linux-x64 to
work with Cassandra 3.0.
OpsCenter logs have the following:
2015-11-26 02:17:39+0300 [] INFO: Starting factory

How can we switch to protocol_version to 4?
Does OpsCenter officially support the latest version of Cassandra?
Did anybody try to setup it?
Please advice. Thank you!
