Description

When running hadoop-cassandra jobs with range queries over ghost keys, the ColumnFamilyRecordReader throws an exception if the last key in a slice_range query is a ghost key.

This seems to be related to changes made in CASSANDRA-2855 to prevent ghost keys appearing in a hadoop map.

The call stack trace is attached.

I made a one-line change to ColumnFamilyRecordReader.java, which seems to solve this issue for us.
