I figured out the problem. The DELETE query only works if the column used in the WHERE clause is also the first column used to define the PRIMARY KEY.

I guess the reason is below statement. " a table must define at least one column that is not part of the PRIMARY KEY as a row exists in Cassandra only if it contains at least one value for one such column " Please check this document here<http://cassandra.apache.org/doc/cql3/CQL.html#createKeyspaceStmt>.
