While migrating to the latest Pig version we have seen a general issue when using nested Avro records on Tez:
The setup is
Pig script group_person.pig
Execution on Tez
Execution on mapred
I am going to attach the complete log files of both runs.
I assume that the Pig script should work regardless of Tez or mapreduce? Is there any underlying change when migrating to Tez which makes the schema invalid?
