I picked up the script */etc/init.d/cassandra* from the net. Not sure if
tarball installation includes such a script. It should.
This script is using the following line:
*pid_file=/var/run/cassandra/cassandra.pid*
But, there is no such *.pid* file that I can find. I am starting Cassandra

I need to shutdown an old Apache Cassandra server for good. Running 3.0.x.
Any way I can determine if anyone is still connecting to the Cassandra
instance running on this server?
Thanks

I am currently running Open Source Apache Cassandra 3.11.1 on RedHat 7.7.
But, need to upgrade the OS to RedHat to 7.9 or 8.x.
The site
cassandra.apache.org/doc/latest/cassandra/getting_started/installing.html
has listed "CentOS & RedHat Enterprise Linux (RHEL) including 6.6 to 7.7".
FYI.
*primary key (partition, clustering1, clustering2)*
So, the partitioning key has three columns. You need to specify values for
all three columns. For clustering columns, you need another parenthesis
like *primary key (partition, (clustering1, clustering2))*

Following:
https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsAddDCToCluster.html
Trying to avoid impact on existing DCs. Have 2 questions:
2. Configure the keyspace and create the new datacenter:
a. Use ALTER KEYSPACE to use the NetworkTopologyStrategy for the following
Anyone is aware of a blog/reference/doc that can give me step by step to
accomplish this? Appreciate the help. Thanks in advance!

I have script that parses "nodetool status" output and emails alerts if any
node is down. So, when I stop cassandra on a node for maintenance, all
nodes stats emailing alarms.
Any way to temporarily make the node under maintenance invisible from
"nodetool status" output?
Thanks
