Subject Re: The stability of Hadoop jobs outputting to Cassandra
Date Mon, 16 Aug 2010 01:05:01 GMT
Status: Fixed, Fix version: 7.0 beta 1 means it's in the beta1 that
was just released, although is open to change
the API slightly.  Either way, it won't be backported to 0.6.

But you can write to Cassandra from the Hadoop job just fine w/o an
OutputFormat.  Just create a Thrift connection in your reduce job.
