C* 1.2.2 vs Raspberry Pi
Stupidly I've locked myself out of JIRA and it doesn't seem to want to send me a password reset so I'll send this bug report here.
As you guys may know I'v been running C* on a Raspberry Pi cluster for experimental and educational reasons. It seems the startup script is borked for 1.2.2 when using JDK1.8 (early release) on the PI.
In Cassandra-env.sh lines 206-208
if [ "$JVM_VERSION" \> "1.7" ] ; then
JVM_OPTS="$JVM_OPTS -XX:+UseCondCardMark"
fi
Are causing C* to not start on the Pi. It's reporting :
Unrecognized VM option 'UseCondCardMark'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
It looks like this change came in for 1.2.2

Yep,
I did remove it and all was well. However it is a gotcha for anyone trying C* on the Pi so a better solution is probably needed (conditionally removal)

It's an optimisation flag, and not applicable to the to the 1.x JVM's
should be fine to remove it.

Mike,
I'll see if there is a conditionally way of removing it. It seems to be the jdk1.8 for arm (hard float) thats missing the option ATM so it could effect other ARM devices at some point.

This was due to
https://issues.apache.org/jira/browse/CASSANDRA-4366
Should be safe to remove this when running on a you Raspberry Pi as it is
a performance change for the JVM and I guess not supported on whatever
version is supported on your distro for the Pi.
