Apache Spark is an open-source cluster computing framework originally developed in the AMPLab at UC Berkeley. In contrast to Hadoop's two-stage disk-based MapReduce paradigm, Spark's in-memory primitives provide performance up to 100 times faster for certain applications. By allowing user programs to load data into a cluster's memory and query it repeatedly, Spark is well-suited to machine learning algorithms.

## Installation

Install the apache-sparkAUR package.

## Configuration

Some environment variables are set in `/etc/profile.d/apache-spark.sh`.

ENV | Value | Description
--- | --- | ---
PATH | `$PATH:/opt/apache-spark/bin` | Spark binaries

You may need to adjust your `PATH` environment variable if your shell inhibits `/etc/profile.d`:

    export PATH=$PATH:/opt/apache-spark/bin

## Enable R support

The R package sparkR is distributed with the package but not built during installation. To connect to Spark from R you must first build the package by running

    # $SPARK_HOME/R/install-dev.sh

as described in `$SPARK_HOME/R/README.md`. You may also wish to build the package documentation following the instructions in `$SPARK_HOME/R/DOCUMENTATION.md`.

Once the sparkR R package has been built you can connect using `/usr/bin/sparkR`.
