> For footer cache PPD to metastore, we'd need a method to do the PPD. Tiny item to create
it on OrcInputFormat.
> For metastore path, these methods will be called from expression proxy similar to current
objectstore expr filtering; it will change to have serialized sarg and column list to come
from request instead of conf; includedCols/etc. will also come from request instead of assorted
java objects. 
> The types and stripe stats will need to be extracted from HBase. This is a little bit
of a problem, since ideally we want to be inside HBase filter/coprocessor/.... I'd need to
take a look to see if this is possible... since that filter would need to either deserialize
orc, or we would need to store types and stats information in some other, non-ORC manner on
write. The latter is probably a better idea, although it's dangerous because there's no sync
between this code and ORC itself.
> Meanwhile minimize dependencies for stripe picking to essentials (and conf which is easy
to remove).
