Hi
At the end, we have solved the problem deleting also the Opscenter keyspace
from the cluster and restarting the opscenter. Then the retry attemps to the
old nodes in the cluster disappeared.

Hi
We were having some issues with different versions in our cluster and the info
which appear in Opscenter. We decide to delete the datastax-agents in each of
the nodes and delete the cluster from the opscenter.
But I still see on the opscenter logs attemps to retry connections to the nodes

The MySQL is there just to save the state of things. I suppose it very

Can't we use zoo keeper for leader election in Cassandra and based on who is
leader ..run azkaban or any app instance for that matter on that Cassandra
server. I'm thinking that I can copy the applocation folder to all nodes and
then determine which one to run using zookeeper. Is that possible ?
Hi
I am not familiar with Azkaban and probably a better question to the
Azkaban community IMO. But there seems to be two modes (
http://azkaban.github.io/azkaban/docs/2.5/) one is solo and one is
two-server mode, but either way I think still SPOF? If there is no
