-----------------------------------------------

    Status: Open  (was: Patch Available)

MAPREDUCE-5193 is committed, let's see if Jenkins is okay this time.

In the while, can you please fix the javadoc like Karthik says.

Also, shall we rename driverV2 to something like run() or runDriver()?

> M/R examples are run through ProgramDriver.driver. ProgramDriver.driver returns void in hadoop-1, while it returns int in hadoop-2. Therefore, the function signatures in the example jar and yarn are incompatible.
