Re: Cassandra 1.1.1 on Java 7
So, my experiment didn't quite work out.

ruuning for a while, you should set the -Xss to more than 160k when you using jdk1.7.

Cassandra 1.1.1 on Java 7
Has anyone tried running 1.1.1 on Java 7? I know Datastax does not recommend it for DSE, is there a reason why ? Regards, Oleg
