----------------------------
Issue Type: Improvement (was: Sub-task)
Parent: (was: PIG-3446)
> Generating Splits in Tez should be configurable to AM or client
> ---------------------------------------------------------------

> Key: PIG-3751

> Project: Pig
> Issue Type: Improvement
> Components: tez
> Reporter: Rohini Palaniswamy

>
> 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.
