git commit: Fix two download suggestions in the docs:

[pw...@apache.org]

Repository: spark
Updated Branches:
  refs/heads/master 1e829905c -> 7b978c1ac


Fix two download suggestions in the docs:

1) On the quick start page provide a direct link to the downloads (suggested by @pbailis).
2) On the index page, don't suggest users always have to build Spark, since many won't.

Author: Patrick Wendell <pw...@gmail.com>

Closes #662 from pwendell/quick-start and squashes the following commits:

-# Building

-Spark uses [Simple Build Tool](http://www.scala-sbt.org), which is bundled with it. To compile the code, go into the top-level Spark directory and run
-
-    sbt/sbt assembly
-
-For its Scala API, Spark {{site.SPARK_VERSION}} depends on Scala {{site.SCALA_BINARY_VERSION}}. If you write applications in Scala, you will need to use a compatible Scala version (e.g. {{site.SCALA_BINARY_VERSION}}.X) -- newer major versions may not work. You can get the right version of Scala from [scala-lang.org](http://www.scala-lang.org/download/).

-# A Note About Hadoop Versions
-
-Spark uses the Hadoop-client library to talk to HDFS and other Hadoop-supported
-storage systems. Because the HDFS protocol has changed in different versions of
-Hadoop, you must build Spark against the same version that your cluster uses.
-By default, Spark links to Hadoop 1.0.4. You can change this by setting the
-`SPARK_HADOOP_VERSION` variable when compiling:
-
-    SPARK_HADOOP_VERSION=2.2.0 sbt/sbt assembly
-
-In addition, if you wish to run Spark on [YARN](running-on-yarn.html), set
-`SPARK_YARN` to `true`:
-
-    SPARK_HADOOP_VERSION=2.0.5-alpha SPARK_YARN=true sbt/sbt assembly
-
-Note that on Windows, you need to set the environment variables on separate lines, e.g., `set SPARK_HADOOP_VERSION=1.2.1`.

 This tutorial provides a quick introduction to using Spark. We will first introduce the API through Spark's interactive Scala shell (don't worry if you don't know Scala -- you will not need much for this), then show how to write standalone applications in Scala, Java, and Python.
 See the [programming guide](scala-programming-guide.html) for a more complete reference.
 
-To follow along with this guide, you only need to have successfully built Spark on one machine. Simply go into your Spark directory and run:
-
-{% highlight bash %}
-$ sbt/sbt assembly
-{% endhighlight %}
+To follow along with this guide, first download a packaged release of Spark from the
+[Spark website](http://spark.apache.org/downloads.html). Since we won't be using HDFS,
+you can download a package for any version of Hadoop.
