Spark is Originally developed at the University of California, Berkeley's, and later donated to Apache Software Foundation. In February 2014, Spark became a Top-Level Apache Project and has been contributed by thousands of engineers and made Spark as one of the most active open-source projects in Apache.
Pandas API on Spark
Commonly used by data scientists, pandas is a Python package that provides easy-to-use data structures and data analysis tools for the Python programming language. However, pandas does not scale out to big data. Pandas API on Spark fills this gap by providing pandas equivalent APIs that work on Apache Spark .
