Hector Client Exception : InvalidRequestException(why:Expected 8 or 0 byte long (9))

We are getting the following kind of exception due to a small mistake that we do in creating column families in cassandra. I had created the column family with providing
comparator type as LONG.

But once i try to insert columns having String values as column names it throws this error.

Solution: Drop the created column family using cassandra-cli
create the Column Family with appropriate comparator type
