-------------------------------
Summary: Pig Avro Writer: Unsupported type in record:class
java.lang.String
Key: PIG-3358

Project: Pig
Issue Type: Bug
Components: piggybank
Affects Versions: 0.11.1
Reporter: Nick White
Attachments: TestTypeInference.java
Attached test case gives the exception below - the avro writer always fails
when writing to a schema with a single field (I've only tested with string
fields though).
