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

Should be fine, just get the java and kernel versions and kernel tuning params as close as possible

Hi all,

 

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.

 

Best,
