 With BulkoutputFormat in Cassandra 1.2.18, if any streaming errors occured, 
 the hadoop task would fail. This doesn't seem to happen with 2.0.12.
 I have a hadoop map task that use BulkoutputFormat. If one of the cassandra 
 nodes I'm writing to is down, I'm getting the following syslog output from 
 the map task:
