Subject cassandra python driver routing requests to one node?
Date Mon, 14 Nov 2016 05:21:53 GMT
We have an odd situation where all of a sudden of our cluster started
seeing a disproportionate number of writes go to one node. We're using the
Python driver version 3.7.1. I'm not sure if this is a driver issue or
possibly a network issue causing requests to get routed in an odd way. It's
not absolute, there are requests going to all nodes.

Tried restarting the problematic node, no luck (those are the quiet
periods). Tried restarting the clients, also no luck. Checked nodetool
status and ownership is even across the cluster.

Curious if anyone's seen this behavior before. Seems like the next step
will be to debug the client and see why it's choosing that node.
