Daniel Dai commented on PIG-4894:
---------------------------------
Understand, can you put a comment on
"pig.tez.opt.union.unsupported.storefuncs"? New code should use
StoreFunc.supportsParallelWriteToStoreLocation instead.
> Add API for StoreFunc to specify if they are write safe from two different
> vertices

> Currently this is done with config settings. Having a programmatic API will
> let people writing StoreFunc to specifically state whether they support it or
> not. Added the method to StoreFunc instead of creating a new interface. If
> it is a new interface, then the StoreFunc implementation cannot be used with
> older versions of Pig.
> When we drop JDK 7 support (hopefully in another year), will move this as a
> default method to StoreFuncInterface as JDK 8 supports that.
