Mohit Sabharwal commented on PIG-4788:
--------------------------------------
[~kellyzly], if you change {{PigSplit}} to extend {{FileSplit}}, will
{{PigInputFormat}} still work with non-file splits like CombineFileSplit, etc. ?
Can we instead use {{FileSplit}} when we create the record reader in
{{PigInputFormatSpark}}, instead of {{PigSplit}} ? That way we could isolate
the change in Spark specific code.
> the value BytesRead metric info always returns 0 even the length of input
> file is not 0 in spark engine
