satish babu krishnamoorthy updated CASSANDRA-3056:
--------------------------------------------------

    Attachment: CASSANDRA-3056-2.txt

Updated the patch to set HeapDump in cassandra-env.sh, 
this value is parsed in the following order.
1) look for jvm_heap_dump_directory in cassandra.yaml
2) if jvm_heap_dump_directory is not set in cassandra.yaml, use /tmp

> 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.
