This is used to find methods in the Scala API that
need to be ported to the Java API. To use it:
./run spark.tools.JavaAPICompletenessChecker
Conflicts:
project/SparkBuild.scala
run
run2.cmd
The previous version assumed that a CLASSPATH environment variable was
set by the "run" script when launching the process that starts the
ExecutorRunner, but unfortunately this is not true in tests. Instead, we
factor the classpath calculation into an extenral script and call that.
NOTE: This includes a Windows version but hasn't yet been tested there.
