> Tez provides way to cache objects with Vertex scope. We can use it to 
>   1) caching the replication join map constructed instead of reading from multiple broadcast inputs from one or more vertex and reconstructing it
>   2) Cache the map in WeightedRangePartitioner. Thought the quantilefile is only one brodcast input from one vertex still it would be faster to use the local cache.
