Rohini Palaniswamy commented on PIG-4674:
-----------------------------------------
{code}
+ byte valueType = DataType.BYTEARRAY;
.....
+ if (valueType == DataType.BYTEARRAY || valueType ==
input.getFields().get(i).type) {
+ valueType = input.getFields().get(i).type;
+ } else {
+ valueType = DataType.BYTEARRAY;
+ break;
+ }
{code}
should be
{code}
+ Byte valueType = null;
+ if (valueType == null)) {
+ valueType = input.getFields().get(i).type;
+ } else if (valueType != input.getFields().get(i).type) {
+ valueType = DataType.BYTEARRAY;
+ break;
+ }
{code}
Without that if we had a0,a1,a2,a3 with a1 as bytearray and a3 as int, it will
become map[int] instead of map[bytearray].
> TOMAP should infer schema
