Hi all.
Recently we made a change to our production env c* cluster (2.1.18) -
placing the commit log to the same SSD where data is stored, which needs
restarting all nodes.
Before restarting a cassandra node, we ran the following nodetool utils:
$ nodetool disablethrift && sleep 5
$ nodetool
Adding more nodes to the cluster fixed the error. Looks like a bug in
python-driver connection pool:
1. The connection pool only has one host
2. A query times out, causing that connection to be removed from the pool
3. Another query executes, but there are no hosts in the pool

Well the python driver you reference is a third party driver, because the
project doesn’t ship official drivers. You may have better luck looking for a
datastax driver support forum, or wait until after the holiday for more people
to be checking email.

Still getting the cassandra.cluster.NoHostAvailable error periodically from
uWSGI hosts. Setting up the connection with postfork:

Dan,
What partitioner are you using and did you just swap out the binary?
Going from 70GB to 200GB+ is extremely odd in any scenario.
Maybe Carlos Rolo has an idea about this issue. He did a ton of 1.2 cluster
upgrades.
As for the tombstones, its the stat for the last five minutes. You could
