> When one uses {{HCatInputFormat}}/{{HCatLoader}} to read from file-formats that support
predicate pushdown (such as ORC, with {{hive.optimize.index.filter=true}}), one sees that
the predicates aren't actually pushed down into the storage layer.
> The forthcoming patch should allow for filter-pushdown, if any of the partitions being
scanned with {{HCatLoader}} support the functionality. The patch should technically allow
the same for users of {{HCatInputFormat}}, but I don't currently have a neat interface to
build a compound predicate-expression. Will add this separately, if required.
