Big Data
Lots of Data (Terabytes or Petabytes)
Big data is the term for a collection of data setsso large and complex that it becomes difficult toprocess using on-hand database managementtools or traditional data processing applications
The challenges include capture, curation,storage, search, sharing, transfer, analysis, andvisualization

What is Spark?
Apache Spark is a general-purpose cluster in-memory computing system
Provides high-level APIs in Java, Scala and Python, and an optimized engine that supports general execution graphs
Provides various high level tools like Spark SQL for structured data processing, Mlib for Machine Learning and more..

Why Spark?
Cluster Manager
Deployment
via YARN
The Spark framework can be deployed through Apache Mesos, Apache Hadoop via Yarn, or Spark’s own cluster manager.
