             Summary: 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
            Priority: Critical


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.
