Subject [jira] [Commented] (PIG-2579) Support for multiple input schemas in AvroStorage
Date Sat, 13 Oct 2012 01:29:03 GMT

    [ https://issues.apache.org/jira/browse/PIG-2579?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13475488#comment-13475488

Cheolsoo Park commented on PIG-2579:
------------------------------------

@Santhosh,
I think that you omitted two files:
contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/storage/avro/avro_test_files/expected_testMultipleSchemas1.avro
contrib/piggybank/java/src/test/java/org/apache/pig/piggybank/test/storage/avro/avro_test_files/expected_testMultipleSchemas2.avro

TestAvroStorage is failing due to missing files. Can you please commit them to trunk and brach-0.11?

Thanks!

> 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 (avro_storage_union_schema_test.tar.gz): run
create_avro1.pig, followed by create_avro2.pig, followed by read_avro.pig.
