Support for multiple input schemas in AvroStorage
-------------------------------------------------
Key: PIG-2579
URL: https://issues.apache.org/jira/browse/PIG-2579
Project: Pig
Issue Type: New Feature
Components: piggybank
Reporter: Stan Rosenberg
Priority: Minor
Attachments: avro_storage_union_schema.patch,
avro_storage_union_schema_test.tar.gz
This is a barebones patch for AvroStorage which enables support of multiple
input schemas. The assumption is that the input consists of avro files having
different schemas that can be unioned, e.g., flat records.
A simple illustrative example is attached: run create_avro1.pig, followed by
create_avro2.pig, followed by read_avro.pig.
