FYI... we finally got around to releasing a version of Virgil that includes the ability to deploy jobs to remote Hadoop clusters running against Cassandra Column Families.
http://brianoneill.blogspot.com/2012/01/virgil-remote-hadoop-job-deployment-via.html This has enabled an army of people to write and deploy Hadoop jobs against our Cassandra cluster. (Literally, we'll probably have 100 M/R jobs by the end of the month) Yes, we still plan to implement a javascript engine as well, but first we intend to tackle Triggers for indexing, data replication and "materialized views". -brian -- Brian ONeill Lead Architect, Health Market Science (http://healthmarketscience.com) mobile:215.588.6024 blog: http://weblogs.java.net/blog/boneill42/ blog: http://brianoneill.blogspot.com/
