 The purpose of an SPIP is to inform and involve the user community in major improvements to the Spark codebase throughout the development process, to increase the likelihood that user needs are met.
 
 SPIPs should be used for significant user-facing or cross-cutting changes, not small incremental improvements. When in doubt, if a committer thinks a change needs an SPIP, it does.

 This page describes the advantages of the pandas API on Spark (“pandas on Spark”) and when you should use it instead of pandas (or in conjunction with pandas).
 
 pandas on Spark can be much faster than pandas and offers syntax that is familiar to pandas users.  It offers the power of Spark with the familiarity of pandas.

 <p class="answer">
 Spark is a fast and general processing engine compatible with Hadoop data. It can run in Hadoop clusters through YARN or Spark's standalone mode, and it can process data in HDFS, HBase, Cassandra, Hive, and any Hadoop InputFormat. It is designed to perform both batch processing (similar to MapReduce) and new workloads like streaming, interactive queries, and machine learning.

Sign up if you&#8217;d like to support the project! This is a great way to let the world know you&#8217;re using Spark, and can also be helpful to generate leads for recruiting. You can also add yourself when you fill the survey.</p>

Spark won a tie with the Themis team from UCSD, and jointly set a new world record in sorting.</p>
 
 <p>They used Spark and sorted 100TB of data using 206 EC2 i2.8xlarge machines in 23 minutes. The previous world record was 72 minutes, set by a Hadoop MapReduce cluster of 2100 nodes. This means that Spark sorted the same data 3X faster using 10X fewer machines. All the sorting took place on disk (HDFS), without using Spark’s in-memory cache.</p>

 <p>Support has been added for running Spark on YARN 2.2 and newer. Due to a change in the YARN API between previous versions and 2.2+, this was not supported in Spark 0.8.0. See the <a href="/docs/0.8.1/running-on-yarn.html">YARN documentation</a> for specific instructions on how to build Spark for YARN 2.2+. We&#8217;ve also included a pre-compiled binary for YARN 2.2.</p>
