> ----------------------------------------------------------------------------

> Key: PIG-3661
> URL: https://issues.apache.org/jira/browse/PIG-3661
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.11.1
> Reporter: Rohini Palaniswamy
> Assignee: Rohini Palaniswamy
> Fix For: 0.12.1, 0.13.0
>
> Attachments: PIG-3661-1.patch, PIG-3661-2.patch

> To reproduce:
> A =load '/tmp/data' as (a1:int, a2:int, a3:int);
> B = load '/tmp/data1' as (b1:chararray, b2:chararray, b3:chararray);
> store A into '/tmp/out/a' using
> org.apache.pig.piggybank.storage.avro.AvroStorage();
> store B into '/tmp/out2/b' using
> org.apache.pig.piggybank.storage.avro.AvroStorage();
> It either fails in the map job if schema is incompatible, or B gets schema of
> A and B merged leading to incorrect results.
> Reason is schema is stored and accessed from a property of UDFContext without
> using a context signature.
> UDFContext context = UDFContext.getUDFContext();
> Properties property = context.getUDFProperties(ResourceSchema.class);
> String prevSchemaStr =
> property.getProperty(AVRO_OUTPUT_SCHEMA_PROPERTY);
