Philip Thompson updated CASSANDRA-7048:
---------------------------------------
Description:
I've left a Cassandra instance in limbo for the last days, meaning that it has
been happily serving read requests, but I've cut off the data ingress, but I
was doing some read-only development.
After not writing anything to Cassandra for a few days, I got the following
error for the first write to Cassandra:
{code}
Caused by: java.lang.RuntimeException: Cannot get comparator 2 in
org.apache.cassandra.db.marshal.CompositeType(org.apache.cassandra.db.marshal.TimestampType,org.apache.cassandra.db.marshal.UTF8Type).
This might due to a mismatch between the schema and the data read
