Jeremy Hanna commented on CASSANDRA-3056:
-----------------------------------------

Do people generally configure their systems to have enough space in /tmp for the whole Cassandra

> 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.
