How to disable swap in centos 7 cassandra without system wide

[pava...@way2online.co.in]

I am facing many out of memory exceptions in cassandra. So i researched on it and found that swap enabling leads to this issues. But i didn't find any procedure to disable swap only for cassandra not for all applications. I am using cassandra 3.9 version

Hi Pavani,

I believe you should keep one application on one server or you can use VMs otherwise you won't have concrete info like which application is using high memory?

And to disable Swap please refer official docs of Datastax.
