Sent secondary jars to distributed cache of all containers and add the cached jars to classpath before executors start. Tested on a YARN cluster (CDH-5.0). `spark-submit --jars` also works in standalone server and `yarn-client`. Thanks for @andrewor14 for testing! I removed "Doesn't work for drivers in standalone mode with "cluster" deploy mode." from `spark-submit`'s help message, though we haven't tested mesos yet.

YARN DIRECTORY LAYOUT
Hadoop Yarn related codes are organized in separate directories to minimize duplicated code.
-
common : Common codes that do not depending on specific version of Hadoop.
-
alpha / stable : Codes that involve specific version of Hadoop YARN API.
alpha represents 0.23 and 2.0.x stable represents 2.2 and later, until the API changes again.
alpha / stable will build together with common dir into a single jar
