> PIG-4649 added support for blacklisting some storefuncs when applying
> union+store vertex group optimization as HCatStorer was not honoring
> mapreduce.output.basename and hardcoding part file names. Found that some of
> our user StoreFuncs also do that and ended up with partial results. So would
> be good to have a whitelist option as well where you can put StoreFuncs that
> do not mess with mapreduce.output.basename.
