Data is exploded in volume, velocity and variety The need to have faster analytic results becomes increasingly important Support near real time analytics to answer business questions
Features
Easy to use Supporting python. Java and Scala Libraries for sql, ml, streaming General-purpose Batch like MapReduce is included Iterative algorithm Interactive queries and streaming which return results immediately Speed In memory computations Faster than MapReduce for complex application on disks
