I'll be doing a presentation on Cassandra's (0.6+) hadoop integration next week. Is anyone currently using MapReduce or the initial Pig integration?
(If you're unaware of such integration, see http://wiki.apache.org/cassandra/HadoopSupport) If so, could you post to this thread on how you're using it or planning on using it (if not covered by the shroud of secrecy)? e.g. What is the use case? Why are you using Cassandra versus using data stored in HDFS or HBase? Are you using a separate Hadoop cluster to run the MR jobs on, or perhaps are you running the Job Tracker and Task Trackers on Cassandra nodes? Is there anything holding you back from using it (if you would like to use it but currently cannot)? Thanks!
