Example 1: Input: [7, 1, 5, 3, 6, 4] Output: 5

Describes how to setup spark 2.1.0 for use with python (pyspark) via jupyter notebook. Does not assume root access. Uses virtualenv.

Get prebuilt spark

mkdir spark_install && cd spark_install
wget http://d3kbcqa49mib13.cloudfront.net/spark-2.1.0-bin-hadoop2.7.tgz
tar -xzvf spark-2.1.0-bin-hadoop2.7.tgz 
cd spark-2.1.0-bin-hadoop2.7/

Test prebuilt spark (this should open a spark console, use Ctrl+C to exit )

Recently tried this in a CPU-only situation with UBUNTU 14.04 LTS (Trusty). Omitted the GPU parts of the script and had to modify it a bit to get it working. Below is the version that worked for me:


Set up java (dependency for Bazel)
Download jdk 8, for most recent version, go here: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html


mkdir jdk
cd jdk



Following wget gives 'ERROR: 403 Forbidden', so just go to the oracle page to get the tarball.
