> 1) TEZ-752 allows setting list of URIs to get delegation tokens. Set that to make Tez get delegation tokens and calculate input splits on AM
> 2) Try using Tez Grouping of input splits instead of pig.maxCombinedSplitSize grouping.
> Generating splits in AM is supposed to give performance boost. For those case where InputFormat or OutputFormat get delegation tokens and it is not possible to do that, then have a option to generate input splits on client.
