Lefty Leverenz commented on HIVE-7231:
--------------------------------------

[~gopalv], I must have been looking at the wrong patch.  Thanks.

Is the coded ampersand (&amp;) necessary in hive-default.xml.template?  Perhaps a simple
"and" would be clearer.  But that's a mini-nit.

+1 for docs

> Current ORC padding is not optimal because of fixed stripe sizes within block. The padding
overhead will be significant in some cases. Also padding percentage relative to stripe size
is not configurable.
