@Leemoonsoo that is exactly the point. JVM will use first classes found on
the class path. The user can do the following:
export
CLASSPATH_OVERRIDES=/opt/whatever/spark-core_2.10-1.5.1-patched-and-fixed.jar
And then it does not matter what `org.apache.spark` classes (as long as
class version matches) are further down the class path:

The current mechanism does not allow hot patching anything. The only
patching mechanism is recompiling Zeppelin with modified JARs, which maybe
difficult / not doable.
Zeppelin prepends new entries but there is no way to tell it "after all
default prepends, add this at the start". And replying to your 2 comments -
yes, indeed :)
