I am using the Cassandra driver for python in Spyder. I am trying to fetch some data from Cassandra table. Here is my code:

from cassandra.cluster import Cluster
df_filtered_10m=session.execute("some query")

This is all working fine and I am getting the desired results. The problem is that in the console, this message is continuously popping up:

WARNING:cassandra.pool:Error attempting to reconnect to, scheduling retry in 256.0 seconds: [Errno None] Tried connecting to [('', 9042)]. Last error: timed out

I have tried cluster.shutdown but it not working as well. How to get rid of it?

  • I also get the same warnings. I am using version 3.11.2 of cassandra, have installed it on AWS EC2 and accessing it via Python driver. I do get results back but frequently still get the warnings above. Any help will be appreciated. – Ajanta Phatak Oct 4 '18 at 20:49
  • Do you see this IP in the output of nodetool status on the one of the cluster nodes? – Alex Ott Oct 21 '18 at 12:08
