Adam Szita commented on PIG-4798:
---------------------------------
Looks like neither BigIntegers nor BigDecimals can be parsed like this, altough
their lexer definition matches correctly to the notation used above (
https://github.com/apache/pig/blob/trunk/src/org/apache/pig/parser/QueryLexer.g#L380
)
The problem is that these token types are not listed under 'scalar' in
QueryParser.g . Because of this the generated QueryParser.java/scalar() method
will not recognise these types and also no valid transitions are generated in
the appropriate state machine (QuerParser.java/DFA141) from BI or BD types.
On top of this LogicalPlanBuilder.java/parseBigInteger only cuts one character
from "12346BI"-like values - need to adjust this to 2 chars.
[^PIG-4798.patch] will fix this and adds some tests too.
[~daijy], [~jcoveney] can you please take a look?

> For example:
> x < 12345678901234567890
> with x being a biginteger tries to parse the literal as Integer.
> x < 12345678901234567890BI
> "BI" is not recognized
