Bikas Saha commented on TEZ-2840:
---------------------------------
IIRC, the init() was a workaround in Legacy for some Hive use cases where Hive
first wanted to do something before letting the input actually initialize(). So
the base class has an initializeInternal() - does most of the work. this is
called from Base.initialize() - so the normal case works. that is hidden by
Legacy.initilizeInternal(). So the hive case blocks initializeInternal() until
Hive calls init() which then completes the processing.
So it would be useful to investigate the possibility of the main initializer
not having been called by the time this happened.

> Only one path that uses initializeInternal and thus this field actually sets
> it.
