I have a single node cassandra installation on my dev laptop, which is used just for dev / testing.
Recently, whenever I restart my laptop, Cassandra fails to start when I run it via 'sudo service cassandra start'. Doing a tail on /var/log/cassandra/system.log gives this log: *INFO [main] 2016-10-24 07:08:02,950 CommitLog.java:166 - Replaying /var/lib/cassandra/commitlog/CommitLog-6-1476907676969.log, /var/lib/cassandra/commitlog/CommitLog-6-1476907676970.log, /var/lib/cassandra/commitlog/CommitLog-6-1477269052845.log* *ERROR [main] 2016-10-24 07:08:03,357 JVMStabilityInspector.java:82 - Exiting due to error while processing commit log during initialization.* *org.apache.cassandra.db.commitlog.CommitLogReadHandler$CommitLogReadException: Unexpected error deserializing mutation; saved to /tmp/mutation9186356142128811141dat.

It looks like its saying there wasn't enough data to read the field 'board_id', any ideas why that would be?
