---------------------------------------
Assignee: Rohini Palaniswamy
> Configure mapred.min.split.size to be same as pig.maxCombinedSplitSize
> ----------------------------------------------------------------------

> Key: PIG-3903

> Project: Pig

>
> FileInputFormat calculates the split size as
> Math.max(minSize, Math.min(maxSize, blockSize));
> By default pig.maxCombinedSplitSize is 128MB if pig.noSplitCombinaton is not
> specifically turned off. We should set the mapred.min.split.size (if not
> already set by the user) to same as pig.maxCombinedSplitSize, so the
> underlying FileInputFormat itself gives us bigger splits when possible
> instead of pig combining smaller splits.
