Disable converting bytes loading from BinStorage
------------------------------------------------
Key: PIG-1745
URL: https://issues.apache.org/jira/browse/PIG-1745
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.8.0
Reporter: Daniel Dai
Assignee: Daniel Dai
Fix For: 0.8.0
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
