Agreed. I have run clusters with both RHEL5 and RHEL6 nodes.

Subject: [EXTERNAL] Re: Installing a Cassandra cluster with multiple Linux OSs (Ubuntu+CentOS)
Should be fine, just get the java and kernel versions and kernel tuning params as close as possible
Did anyone installed a Cassandra cluster with mixed Linux OSs where some of the nodes were ubuntu 12\14\16 and some of the nodes where CentOS7?
Will it work without issues?
Rational: We have a 40 servers cluster which was originally installed only with Ubuntu servers. Now we want to move to CentOS 7 but the effort of reinstalling the entire cluster + migration to CentOS 7 is not simple. So we thought
about adding new CentOS 7 nodes to the existing cluster and gradually remove the Ubuntu ones.
Would love to read your thoughts.
