------------------------------------------------------------------
Do people generally configure their systems to have enough space in /tmp for
the whole Cassandra heap? What about the cassandra log directory as a default?
/tmp seems fine but this bit us because the heap dump is so big.

> We should be able to designate the path location to put any perf dumps that
> are performed. By Default with this not set the perf dump can occur on the
> root disk and fill the drive.
> Should be able to solve this by simply inserting JVM_OPTS="$JVM_OPTS
> -XX:HeapDumpPath=<path to dir>" into cassandra-env.sh as a default option
> available and set.
