[jira] [Updated] (PIG-2854) AvroStorage doesn't work with Avro 1.7.1

["Cheolsoo Park (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-2854?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Cheolsoo Park updated PIG-2854:
-------------------------------

    Attachment: PIG-2854.patch

Attached is a patch that changes the name of the method in PigAvroDatumWriter from resolveUnion() to resolveUnionSchema() to avoid the conflict.

I tested against Avro 1.5.3, 1.6.3, and 1.7.1.

Thanks!

> PigAvroDatumWriter fails to compile against Avro 1.7.1 with the following error:
> {code}
> /home/cheolsoo/workspace/pig-trunk/contrib/piggybank/java/src/main/java/org/apache/pig/piggybank/storage/avro/PigAvroDatumWriter.java:119: resolveUnion(org.apache.avro.Schema,java.lang.Object) in org.apache.pig.piggybank.storage.avro.PigAvroDatumWriter cannot override resolveUnion(org.apache.avro.Schema,java.lang.Object) in org.apache.avro.generic.GenericDatumWriter; overridden method does not throw java.io.IOException
> protected int resolveUnion(Schema union, Object datum) throws IOException {
> {code}
> The problem is that a new method resolveUnion() is added to GenericDatumWriter in Avro 1.6.x and 1.7.x, but this method conflicts with the one that already exists in PigAvroDatatumWriter.
