Description

I noticed this morning that Cassandra was failing to start, after being shut down on Friday.

ERROR 09:13:37 Exiting due to error while processing commit log during initialization.
org.apache.cassandra.db.commitlog.CommitLogReplayer$CommitLogReplayException: Could not read commit log descriptor in file C:\Program Files\DataStax Community\data\commitlog\CommitLog-5-1465571056722.log

Checking the referenced file reveals it comprises 33,554,432 (32 * 1024 * 1024) NUL bytes.
No logs (stdout, stderr, prunsrv) from the shutdown show any other issues and appear exactly as normal.
Is installed as a service via DataStax's distribution.
