Dmitriy V. Ryaboy commented on PIG-2935:
----------------------------------------
Alan, that won't work -- the error thrown is not NoSuchMethod, but
AbstractMethodError (the abstract method is declared in the new interface, so
the method exists, but has no implementation). These are both children of
IncompatibleClassChangeError , which would capture the case of somehow using
the new PigServer but the old StoreFuncInterface, though that's probably
overkill (I don't know how one would get into such a bind).
> Catch NoSuchMethodError when StoreFuncInterface's new cleanupOnSuccess method
> isn't implemented.

> We should catch a NoSuchMethodError here so that old implementations of
