[SPARK-1753 / 1773 / 1814] Update outdated docs for spark-submit, YARN, standalone etc.
YARN
- SparkPi was updated to not take in master as an argument; we should update the docs to reflect that.
- The default YARN build guide should be in maven, not sbt.
- This PR also adds a paragraph on steps to debug a YARN application.
Standalone
- Emphasize spark-submit more. Right now it's one small paragraph preceding the legacy way of launching through `org.apache.spark.deploy.Client`.
- The way we set configurations / environment variables according to the old docs is outdated. This needs to reflect changes introduced by the Spark configuration changes we made.
In general, this PR also adds a little more documentation on the new spark-shell, spark-submit, spark-defaults.conf etc here and there.

If you wish to +run PySpark on a YARN cluster with Red Hat installed, we recommend that you build the jar elsewhere, +then ship it over to the cluster. We are investigating the exact cause for this. + ## Packaging without Hadoop dependencies for deployment on YARN ## The assembly jar produced by "mvn package" will, by default, include all of Spark's dependencies, including Hadoop and some of its ecosystem projects. On YARN deployments, this causes multiple versions of these to appear on executor classpaths: the version packaged in the Spark assembly and the version on each node, included with yarn.application.classpath. The "hadoop-provided" profile builds the assembly without including Hadoop-ecosystem projects, like ZooKeeper and Hadoop itself. |
