----------------------------------------------------------------
patch against the cassandra-1.1 branch attached.
This does a mark on the buffer, saves off the token value and then resets the
buffer to back to the mark. Downstream users then aren't able to effect the
operation of the iterator.

> Reading the ByteBuffer key from a map job causes an infinite fetch loop
> -----------------------------------------------------------------------

> Key: CASSANDRA-4593
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4593
> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Affects Versions: 1.1.2
> Reporter: Ben Frank

> Reading the ByteBuffer key from a map job empties the buffer. One of these
> key buffers is later used in ColumnFamilyRecordReader to figure out the last
> token that was received, then using that as a start point to fetch more rows.
> With a now empty buffer, the token defaults to the start of the range and
> thus the end of the data is never reached.
