As part of the goal to stop creating assemblies in Spark, this change modifies the mvn and sbt builds to not create an assembly for examples. Instead, dependencies are copied to the build directory (under target/scala-xx/jars), and in the final archive, into the "examples/jars" directory. To avoid having to deal too much with Windows batch files, I made examples run through the launcher library; the spark-submit launcher now has a special mode to run examples, which adds all the necessary jars to the spark-submit command line, and replaces the bash and batch scripts that were used to run examples. The scripts are now just a thin wrapper around spark-submit; another advantage is that now all spark-submit options are supported. There are a few glitches; in the mvn build, a lot of duplicated dependencies get copied, because they are promoted to "compile" scope due to extra dependencies in the examples module (such as HBase). In the sbt build, all dependencies are copied, because there doesn't seem to be an easy way to filter things. I plan to clean some of this up when the rest of the tasks are finished. When the main assembly is replaced with jars, we can remove duplicate jars from the examples directory during packaging. Tested by running SparkPi in: maven build, sbt build, dist created by make-distribution.sh. Finally: note that running the "assembly" target in sbt doesn't build the examples anymore. You need to run "package" for that. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #11452 from vanzin/SPARK-13576.
