Answer 2

This error has more to do with your JRE version than the OS you are running. Setting ThreadPriorityPolicy=42 works in Java 8, but not any major version higher than that.

There is not a current version of Cassandra which uses anything higher than Java 8, so I recommend you ensure that the latest patch of that version is installed.

tl;dr;

• Install Java 1.8
• Try running Cassandra again
