Almost working, still gives odd output when run on my VM, there is likely an error in the compaction code or a non-UTF8 encodable element. Compaction and stringifying takes place in SSTableCassandraRow, ByteBufferUtil.bytesToHex(value) writes odd data in value fields but there is a non-encodable line preventing me from outputing this as a string. This can be run with the following commandline (note that file:// must be used to specify the yaml otherwise it complains that it cannot find it.). : java -Dcassandra.config=file:///etc/cassandra/cassandra.yaml -jar ~/dumpAll.jar /var/lib/cassandra/data/vdna/user ~/ssTableUs.outfile
