ConstantExpression considers (-1.0) as a tuple rather than double
-----------------------------------------------------------------
Key: PIG-2544
URL: https://issues.apache.org/jira/browse/PIG-2544
Project: Pig
Issue Type: Bug
Affects Versions: 0.9.1, 0.10
Reporter: Vivek Padmanabhan
{code}
A = load 'i1' as (a,b,c:double);
B = foreach A generate ((a eq '')?((b eq '')? (-1.0) :(c/100.0)): (c/100.0)) ;
dump B;
{code}
In Pig 0.9 the above script fails with exception : "Unsupported input type for
BinCond: left hand side: tuple; right hand side: double"
The same script works fine with Pig 0.8.
I think the issue is ConstantExpression uses
Util.translateFieldSchema(DataType.determineFieldSchema(val))
which considers (-1.0) as a tuple rather than double in this case.
