Hi There,
I need some suggestions in terms of connecting to the Cassandra cluster
which is deployed on the Kubernetes cluster via the datastax client library.
The idea is to expose Kubernetes Service object for the Cassandra
cluster which can be leveraged by a client which is using the datastax

should consider change the policies (often via setsebool or audit2allow)
to allow the connection. Blindly disable SELinux does solve the issue,
but it isn't a good
Thank you Bowen. Much appreciated.
You were right. I disabled the selinux and I got past that error/page.

$ sudo setenforce 0
## To permanently disable, set SELINUX=disabled in /etc/selinux/config

What do you mean "through the browser"? Is it a php page that runs on
something like Apache/Nginx? If that's the case, and the same code and
the same setup works on Ubuntu 18 but not CentOS 7, I would recommend
you to have a look at the SELinux logs.

Is the cluster up and running?
As your message says "Control connection failed to connect, shutting down

May be you can get some more info from the system.log.

Hi Gupta,
I am running a simple python application that isn’t heavy from point of view of
access to cassandra. The application create a new keyspace, tables and do the
load of data.
The application is an example in python-driver folder.

Are you running heavy load?
I have seen these kinds error application team reporting to us in case when
they have too many connection already setup and they are trying to connect
more applications.
Try to disconnect the applications which are not required and try again ..
Hope this helps...

For your testing, I think put your machine's ip should work.

I have installed Cassandra on a Ubuntu Server but I fail to see it with
either:
ps ax
or
netstat -an | grep 9160
I see a file /etc/init.d/cassandra so I am assuming that it should start up.
What else do I need to do? I have edited cassandra.yaml for all the places
that specifically
The correct object name is "org.apache.cassandra.db:type=StorageProxy"
