we created a keyspace that contained two tables. These tables are
filled with data. For a shutdown of the machine, we performed "nodetool
flush" (and also in a second try "nodetool drain"). After that, we
stopped the Cassandra service with "SigTerm"

We changed nothing after the system stop and restarted the node. The
following error occured during restart.

ERROR 10:14:33 Exiting due to error while processing commit log during 
Unexpected error deserializing mutation; saved to 
/tmp/mutation8563274912263154073dat.  This may be caused by replaying a 
mutation against a table with the same name but incompatible schema.  Exception 
follows: org.apache.cassandra.serializers.MarshalException: Expected 4 byte 
long for date (0)

Before the shutdown, the data was correctly and without errors available within 
the database.

Any ideas about that error?

Thank you in advance.
