> Key: CASSANDRA-4466

> Project: Cassandra

> Components: Hadoop
> Affects Versions: 1.1.2
> Reporter: Niel Drummond

> 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.
