Mridul Muralidharan commented on PIG-1745:
------------------------------------------
Since this is a backwardly incompatible change, some release notes indicating
how users can continue to rely on earlier behavior (when the data being casted
is indeed a long in the example in desc) would be good - assuming it is still
possible to do so.
If it is totally removed as an option, it is very unfortunate and drastically
diminishes the value of BinStorage.

> If we load bytes from BinStorage, we don't actually know how we get these
> bytes originally, and we will not have a way to cast those bytes. Ideally we
> shall encode caster into BinStorage data file, but we are not there yet.
> Currrently bytesToXXX methods for BinStorage is wrong and it results
> unexpected errors. Eg.
> {code}
> a = load '1.txt' as (a0, a1, a2);
> store a into '1.bin' as BinStorage();
> a = load '1.bin' using BinStorage as (a0, a1, a2);
> b = foreach a generate (long)a0;
> dump b;
> {code}
> The code will run but produce wrong data. It's less confusing if we throw an
> exception in this case.
> Release Notes:
> Pig will throw exception in the case we want to convert bytes loading from
> BinStorage
