Getting Started with Apache Spark

First Steps with Spark – Screencast #1

  • Download spark
  • Extract archive
  • View archive README. Note we’ll use sbt to build spark, Scala must be pre-installed, and SCALA_HOME environment var needs to be set.
    [UPDATED] Looks this video is outdated. The latest spark version (1.5.2) uses maven to build. Install Java and Maven.
  • Start spark build
    spark-archive-home$> sbt/sbt package

    [UPDATED] Run Maven build command…

    spark-archive-home$> build/mvn -DskipTests clean package

    … I did run into consistent errors during this step, which think it has to do with mis-matching java versions. I gave up after a while and just downloaded the pre-compiled spark binaries instead :)

  • Download & extract Scala required version (from spark source README)
    [UPDATED] looks like maven takes care of building scala source and it already comes working with the pre-compiled binary distros.
  • Set SCALA_HOME env var by creating a conf/ file using the spark distro’s conf/ file as a template (as described in spark distro README) OR edit your user .profile file to export SCALA_HOME env var with correct scala exec path.
    $> cp conf/ conf/
    $> vi conf/
    $> export SCALA_HOME=/opt/spark-1.5.2-bin-hadoop2.4 ##add this line inside

    [UPDATED] Skipped SCALA_HOME env var step. Looks like it’s unnecessary.

  • Log4j logging level setup by using sparks log4j template….
    $>  cp conf/ conf/
    $> vi conf/
    log4j.rootCategory=ERROR, console ##edit this line inside
  • Start spark shell…
    $> bin/spark-shell
  • Open Spark Quick Start guide and walk through scala with spark examples.
