Apache Cassandra 3.0
Released on 2021-02-01, and supported until 4.1 release (April 
2022).


Would the wording "… and supported until 4.1.0 release (May-June 2022)." be 
enough?
(it would be nice to keep the text brief on this page)

Fwd: Re: Problem on setup Cassandra v4.0.1 cluster

[onmstester onmstester]

Once again it was related to hostname configuration (I remember had problem 
with this multiple times before even on different applications), this time the 
root cause was a typo in one of multiple config files for hostname (different 
name on /etc/hostname with /etc/hosts)! I fixed that and now there is no 
problem.



I wonder how Cassandra-3.11 worked?!



P.S: Default dc name in version 4 was changed to datacenter1 (from dc1) and it 
seems to cause a bit of problem with previous configs(default one in rack-dc 
conf still is dc1).


Thank you

TP stats indicate pending gossip. Check that the times are synchronised on both 
nodes (use NTP) since it can prevent gossip from working.



I'd also suggest looking at the logs on both nodes to see what other WARN and 
ERROR messages are being reported. Cheers!

Re: Problem on setup Cassandra v4.0.1 cluster

[Bowen Song]

Since 3.x worked and 4.x didn't, it is most likely caused by clock out 
of sync between servers. Cassandra 3.x by default has cross node timeout 
disabled, and Cassandra 4 has changed the default to enabled. Check the 
system time on both servers are accurate. Use NTP to prevent this from 
happening again.

Re: 4.1 Release Date

[McIntyre, Sean]

Michael,

Thank you very much, that level of detail is what I was hoping to get.  From 
your response, it sounds as though a formal 4.1.x release would not be before 
May and there is an excellent chance it would be June or later.  May I ask that 
the info posted on the Downloads page get an update to reflect this more 
current timeline?  Right now, it says the following:

Apache Cassandra 3.0
Released on 2021-02-01, and supported until 4.1 release (April 
2022).

Thanks again, very helpful...

We are trying to get on 3.11.x prior to earlier releases going eol and a more

if it is the classic s/w answer of eom.  Thanks…

Apologies Sean, this is not something the community can provide an exact 
date on.

The community's agreed plan is to make the first cut of 4.1 in May. This 
may be 4.1-alpha1 or 4.1-beta1. From there the time it takes to get to 4.1-rc1 
and 4.1.0 we do not know.

Also, my understanding is that the community will maintain 3.0.x until 
4.1.0 is formally released.
