Re: Pig Schema contains a name that is not allowed in Avro
Hey Johannes!
Have you solved the problem? I also see it.
But I don't see it when I use the schema as a string to AvroStorage
parameter. I see it only when I try to use an external schema file. And if
I specify a non-existent external schema file, the error is the same.
