Dmitriy V. Ryaboy commented on PIG-2239:
----------------------------------------
We can check if the hadoop command is available, and fall back to the old
method with a warning if it is not. That will let us work in places that have
the hadoop jar but not the hadoop scripts, etc.
For reducing size of the job jar in other similar cases, I've actually taken to
keeping a tiny jar around, and invoking hadoop jar on that, while ensuring that
my real jar is on the classpath and in libjars. Otherwise all the unnecessary
unjarring Hadoop does gets really annoying.
> Pig should use "bin/hadoop jar pig-withouthadoop.jar" in bin/pig instead of
> forming java command itself
