Key: PIG-463
URL: https://issues.apache.org/jira/browse/PIG-463
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Pradeep Kamath
Assignee: Pradeep Kamath
Fix For: types_branch
If a map in pig (say returned from a UDF) has a key with the value being a string, then a lookup of that key being used in a context which expects a string will cause an implicit cast to a string. This is because the Pig frontented (logical layer) thinks of all map "values" as bytearrays and hence introduces a Cast to convert the bytearray to string. The POCast class then assumes its input is a DataByteArray and first tries to cast its input to DataByteArray. This fails because the object in the input to the case which is the value in the map is in fact already a string. So in these cases, we should not try to cast but just return the input object in the POCast.
