Only brand new RDDs (e.g. parallelize and makeRDD) now use default
parallelism, everything else uses their largest parent's partitioner
or partition size.
- Edited quick start and tuning guide to simplify them a little
- Simplified top menu bar
- Made private a SparkContext constructor parameter that was left as
public
- Various small fixes
throughout the docs: SPARK_VERSION, SCALA_VERSION, and MESOS_VERSION.
To use them, e.g. use {{site.SPARK_VERSION}}.
Also removes uses of {{HOME_PATH}} which were being resolved to ""
by the templating system anyway.
