--------------------------------------------

             Summary: Empty CommitLog prevents restart
                 Key: CASSANDRA-12539
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12539
             Project: Cassandra
          Issue Type: Bug
            Reporter: Stefano Ortolani


A node just crashed (known cause: CASSANDRA-11594) but to my surprise (unlike other time) restarting simply fails.

Checking the logs showed:

Deleting the empty file fixes the problem.
