The justification for breaking compatibility was that the API was marked
@Private. We're working to fix this in YARN-1931 - the missing API will be
added back in for 2.4.1 and further. There's still some discussion there on
whether the make the API public. The issue with the old API is that it
couldn't handle Windows clients submitting to Linux servers (and vice versa).
So we'll want to switch to the new API anyway to avoid this issue. If the API
is made public, we can use reflection to call it going forward. Else, we'll
need to go with @xgong 's approach.
