OpsCenter doen not work with Cassandra 3.0

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 
<cassandra.io.twistedreactor.TwistedConnectionClientFactory instance at

CreateClusterConfController: Unable to connect to cluster. Error is:

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!

Hi Sergey,

There were some changes of the system schema tables in the released version
of Cassandra 3.0 that are preventing tools like OpsCenter and DevCenter to
connect. We are working on releasing updated versions that are fully
compatible with C 3.0.

thanks for your understanding,
