We are running OpenJDK7 with G1GC and encountered no issues so far. We took
the tuning parameters from the Cassandra 3.0 branch.

IMHO G1 is still buggy on JDK8 (based solely on being subscribed to the gc-dev 
mailing list)… I think JDK9 will be the one.

Possibly for existing apps… we’re running G1 for everything except
Elasticsearch and Cassandra and are pretty happy with it.

Running Cassandra on Java 8 u60..

2015-09-25 Thread Kevin Burton 
Any issues with running Cassandra 2.0.16 on Java 8? I remember there is
long term advice on not changing the GC but not the underlying version of
Java.

Thoughts?

I think those were referring to Java7 and G1GC (early versions were buggy).

Thoughts?
