---------------------------------------

             Summary: Casting numeric value that does not fit in integer data type produces
incorrect result
                 Key: DRILL-2015

t1.json
{code}
{ "a1": 1 ,    "b1" : 1}
{ "a1": 2 ,    "b1" : 1}
{ "a1": 2 ,    "b1" : 2}
{ "a1": 3 ,    "b1" : 2}
{ "a1": 5000147483647 , "b1" : 3}

We should throw an error, this is technically data corruption.
