["Paul Mazak (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-4570?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Mazak updated PIG-4570:
----------------------------
    Attachment: PIG-4570_2.patch

Ok. Added a test case to TestAvroStorage, along with RecordPojo.avsc and RecordPojo.java.  The test specifies the "-c org.apache.pig.builtin.avro.code.java.RecordPojo" arg.  The class was generated by avro-tools and checked into the test code base.
{quote}
java -jar avro-tools.jar 
compile schema test\org\apache\pig\builtin\avro\schema\RecordPojo.avsc test
{quote}

> When you are managing Avro Schemas in your source code and you have the Java classes to serialize/deserialize Avro, it would be easier to do something like:
> {quote}
> store a into 'tmp/myuser' using AvroStorage(null, '-schemaclass com.myco.MyUser')
> {quote}
> Rather than passing as the first agurment, the entire Avro schema json in the pig script, or keeping a (potentially outdated) set of Avro schema files in HDFS for the -schemafile option.
> If your classpath is already aware of how to serialize/deserialize the Avro data, it would be good to leverage that with a fully qualified classname.
