> This patch aims at adding support for vectorize read of data from Druid to Hive.
> [~t3rmin4t0r] suggested that this will improve the performance of the top level operators
that supports vectorization.
> As a first cut am just adding a wrapper around the existing Record Reader to read up
to 1024 row at a time. 
> Future work will be to avoid going via old reader and convert straight the Json (smile
format) to Vector primitive types.
