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

             Summary: Avro files with stringType set to String cannot be read by the AvroStorage LoadFunc
                 Key: PIG-3297
                 URL: https://issues.apache.org/jira/browse/PIG-3297
             Project: Pig
          Issue Type: Bug
          Components: piggybank
    Affects Versions: 0.11.1
            Reporter: Niels Basjes


When an Avro file is created there exists the option to set the "String Type" to a different class than the default Utf8.
A very common situation is that the "String Type" is set to the default String class.

When trying to read such an Avro file in Pig using the AvroStorage LoadFunc from the included piggybank this gives the following Exception:

Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to org.apache.avro.util.Utf8
        at org.apache.pig.piggybank.storage.avro.PigAvroDatumReader.readString(PigAvroDatumReader.java:154)
        at org.apache.avro.generic.GenericDatumReader.read(GenericDatumReader.java:150)
