MapR Brings Spark In-Memory Analysis To Hadoop

MapR adds Apache Spark to its Hadoop distribution to power machine learning plus ad hoc, graph, and streaming analysis. Databricks partners on support.

MapR announced Thursday that it's bringing Apache Spark software and support to its Hadoop distributions. Software and support is available immediately through all of its Hadoop distributions through a partnership with Spark backer Databricks.

Spark is quickly establishing itself as a leading environment for doing fast, iterative in-memory and streaming analysis. The software can run stand-alone in a clustered environment, but it can also run on top of Hadoop by way of the YARN resource manager introduced last year in Hadoop 2.0.

The Spark software stack was created and turned over to open source by Databricks, a commercial company that certifies related software and offers installation and ongoing management support. The stack includes the core data-processing engine, an interface to Hive for interactive querying, Spark Streaming for streaming data analysis, and growing libraries for machine-learning and graph analysis.

"People are really excited about using Spark because it's a way around traditional multi-step processing on Hadoop," said Anoop Dawar, senior director of product management at MapR. "Spark provides a fast way to do iterative machine-learning and model-learning because it caches results in memory for continuous analysis."

MapR adds the Spark stack, highlighted in gray, to its list of more than 20 supported Apache open source projects.

Spark also supports interactive, ad hoc exploration of data, using Hive, for example, and streaming analysis applications such as network threat detection and fraud risk analysis. In the streaming role it's used in combination with tools such as Kafka and Flume.

Cloudera became was the first Hadoop distributor to add Spark software and support with its Cloudera Enterprise release in February. MapR will ship Spark software with its M3, M5, and M7 software distributions and offers optional Spark support. MapR will handle first-level and second-level support for software installation and day-to-day management. When higher-level expertise is required, MapR can call in Databricks domain experts, but MapR maintains case management so "it's not a cold handoff," according to Dawar.

Clarification of Spark's Origin
MapR's announcement is indeed an important milestone in the progress of Spark as an enterprise solution.   However I need to correct one key point in your article.  Spark, Shark, Spark Streaming, ML-lib etc were all developed at the UC Berkeley AMPLab ( and have been open source since their inception.  They are components of the Berkeley Data Analytics Stack (BDAS) which has been and continues to be developed by students and researchers in the AMPLab.   Databricks is a company that spun out of the lab and that was founded by many of the key developers of Spark.

The powerful Hadoop platform
Hadoop is one of those brilliantly simple platforms -- a distributed file system on top of distributed processing combined with data mapping -- on which many increasingly sophisticated systems may be built. Good description here of Spark streaming analysis; it's probably one of them.
