Brisk is a distribution of Apache Cassandra, Hadoop, Pig and Hive, enabling MapReduce jobs to be executed across a scalable, peer-to-peer storage cluster. A Cassandra-based filesystem called CassandraFS replaces HDFS (and avoids the single point of failure in HDFS, the NameNode). MapReduce jobs can work on files stored in CassandraFS, or on the fine-grained rows and columns within Cassandra.
