Comment:
Updated the Streaming section.

  As of 0.7, there is a basic mechanism included in Cassandra for outputtin=
g data to Cassandra.  The `contrib/word_count` example in 0.7 contains two =
reducers - one for outputting data to the filesystem and one to output data=
 to Cassandra (default) using this new mechanism.  See that example in the =
latest release for details.

- As of 0.7, there is support for [[http://hadoop.apache.org/common/docs/r0=
.20.0/streaming.html|Hadoop Streaming]].  For examples on how to use Stream=
ing with Cassandra, see the contrib section of the Cassandra source.  The r=
elevant tickets are [[https://issues.apache.org/jira/browse/CASSANDRA-1368|=
CASSANDRA-1368]] and [[https://issues.apache.org/jira/browse/CASSANDRA-1497=
|CASSANDRA-1497]].
+ Hadoop output streaming was introduced in 0.7 but was removed from 0.8 du=
e to lack of interest and the additional complexity it added to the Hadoop =
integration code.  To use output streaming with 0.7.x, see the contrib dire=
ctory of the source download of Cassandra.
