Rohini Palaniswamy commented on PIG-4674:
-----------------------------------------
TOMAP also accepts a bag with 'pair' tuples (i.e. tuples with a 'key' and a
'value'). That is not handled. Can also simplify code to
{code}
+ Byte valueType = null;
+ if (input != null && input.getFields()!=null) {
if (input.size() == 1) {
//Code for bag of tuple pairs case. Get valueType of the
second field in tuple
} else {
valueType = input.getFields().get(1).type;
}
+ }
+ Schema s = new Schema(new Schema.FieldSchema(null, DataType.MAP));
+ if (valueType != null && valueType != DataType.BYTEARRAY) {
+ s.getFields().get(0).schema = new Schema(new
Schema.FieldSchema(null, valueType));
+ return s;
+ }
{code}
