DataStax Enterprise (DSE) 4.5 introduces integration with external Hadoop vendors such as Cloudera and Hortonworks, enhancing its analytical capabilities. This feature, known as Bring Your Own Hadoop (BYOH), allows users to install certain Hadoop components from a preferred vendor on a DSE cluster to run analytic jobs directly on Apache Cassandra™ data. The external Hadoop integration is aimed at customers looking for an integrated analytics solution and can be used with the new Apache Spark™/Shark option available as part of DSE 4.5. BYOH nodes are not part of DSE's analytic datacenter, and best practice recommends deploying them in a virtual data center to avoid interference between Cassandra (OLTP) resources and BYOH analytic workloads.
