Im tring t build up an Hawkular Server in Windows 7 - unfortunately this server works with a Cassandra DB - ive installed the newest version and in the starting process of Hawkular I got following error:

Cassandra DB is online and I can connect to localhost:9160 with the Cassandra CQL Shell - but not the hawkular server - have I forgotten something?
From the log, the port Hawkular is trying to use is 9042. Make sure of this setting in your cassandra.yaml
start_native_transport: true
native_transport_port: 9042
The port you are using (9160) is thrift port.
I can only take a stab in the dark with such limited information.
However you said you connected to localhost:9160. In the log it mentions "127.0.0.1:9042".

In my Cassandra cluster of 30 nodes, having datacenter 1, replication factor 3.
We are facing issues when tried to load data into cassandra.
Error from log:

Can someone suggest how to fix these warnings and errors.
Thanks,
Every nodes of the cluster are in Version DSE 6.0.14, they set in ssl mode (listen on port 7001).
We're trying to add a node in version open Sources 4.0 RC1.
We force the port communication on this node:
storage_port: 7001
else the node try to communicate on the 7000 port that is closed.
We encountered the following error, when I try to start the service of the new node :

I don't know if the error come from a mistake in the config of the node oss 4.0 or if there is an incompatibility between the new node version and the version of the existing node in the cluster.
I am trying to setup Datastax OpsCenter.
When I tried to run datastax-agent I get the following error:
Can't connect to Cassandra (All host(s) tried for query failed (tried:
/X.X.X.X1:9042 (com.datastax.driver.core.exceptions.TransportException:

/X.X.X.X6:9042 [only showing errors of first 3 hosts, use getErrors()
for more details])), retrying soon.
Please let me know if any other details are required.
I have 2 node Cassandra cluster with datastax-agent up and running(one seed node) also nodetool status showing healthy.
In the 3 node I have opscenter install and the UI is loading fine with a blank screen, when I saw the var log it's complaining 'NO cassandra connection available for hostlist with a invalid unsupported version'(paster the log details message below). Any help is highly appreciated
2017-02-25 06:33:06+0000 [CLUSTER_NAME] ERROR: Control connection failed to connect, shutting down Cluster: ('Unable to connect to any servers', {'SEED-IP': })
2017-02-25 06:33:06+0000 [CLUSTER_NAME] WARN: No cassandra connection available for hostlist ['SEED-IP'] . Retrying.
I was using an old version of opscenter which was not matching the version of dse. Here is the map for your refference.
Reference: datastax doc
I am facing issue when I try to connect opscenter-agent to opscenter . In UI when we put any node ip it's shows Error creating cluster: Timeout while adding cluster. Please check the log for details on the problem.
In opscenter log I getting below error
