Namit Jain commented on HIVE-533:
---------------------------------
Can you add some constants ? like 1/2 for boolean false/true = may help in some
debugging later on.
Also, it might be useful to add a dump() method which takes the inputbytebuffer
and dumps the structure ?
This can be done in a follow-up later also, may be useful for other serdes also.
> predicate clauses with rand() should not be pushed down
