Cheolsoo Park commented on PIG-3204:
------------------------------------
I have one very minor question. In BoundScript.java, you're not setting
skipParseForBatch in {{registerQuery()}} while you're in {{call()}} and
{{exec()}}. Is this because this particular method is only called by
describe/explain/illustrate, and thus, they don't need this optimization? Or is
there another reason why we shouldn't?
I found it inconsistent and wanted to clarify. Other than that, looks good to
me.

> Currently there are a lot of NN calls made to determine if there is a
> schema file for a path in a LOAD statement. When there is a slow NN(caused by
> whole bunch of other issues), it takes a lot of time for this and we found
> the scripts spending anywhere from 5 mins to 40 mins depending upon the
> script. It seems to be a good place for optimization.
