I use pssh -i -h hosts nodetool for one-offs.
Rolling restart is tricky to automate, but haven't had to yet. If I were
to, I would be sure to do a test connect and query to confirm the node is
up before going to the next one.
For automation I use python fabric.
I too, would be curious what othe
ding to confirm there are no 3.x SSTables left

Thanks Brandon!
Anyone know the upgrade path from 3.x?
https://cassandra.apache.org/doc/latest/cassandra/getting_started/installing.html
Doesn't look like it has specific upgrade instructions.
For instance do we need to run nodetool upgradesstables?
TIA

Maybe a firewall killing a connection?
What does the following show?
cat /proc/sys/net/ipv4/tcp_keepalive_time
cat /proc/sys/net/ipv4/tcp_keepalive_intvl
cat /proc/sys/net/ipv4/tcp_keepalive_probes
