debian packages

Is there a reason why the jvm options are so different in the debian version
from the standard cassandra.in.sh?  The following lines are completely
missing from the init script:
        -XX:TargetSurvivorRatio=90 \
        -XX:+AggressiveOpts \
        -XX:+UseParNewGC \
        -XX:+UseConcMarkSweepGC \
        -XX:+CMSParallelRemarkEnabled \
        -XX:+HeapDumpOnOutOfMemoryError \
        -XX:SurvivorRatio=128 \
        -XX:MaxTenuringThreshold=0 \

I see these in the JVM_EXTRA_OPS line of /etc/defaults/cassandra, but I
don't see where this data is actually passed into the jvm in the init
script.  Am I missing something?

Yes.

Thanks.  I'll apply the patch.  I'm not real familiar with the JVM options,
but I assume that on a production machine I should remove -Xdebug and the
-Xrunjdwp options.

JVM_EXTRA_OPS should be getting passed (they used to be), so this is a
bug. It's been fixed now in SVN (both the 0.6 branch, and trunk); if
you're not running from SVN you can apply the following one-liner:

https://svn.apache.org/viewvc/cassandra/branches/cassandra-0.6/debian/init?r1=940575&r2=940574&pathrev=940575

Thanks for spotting this.
