> AvroReader allows the choice of schema access strategy from such options as
> Use Embedded Schema, Use Schema Name, Use Schema Text, etc. If the incoming
> Avro files will have embedded schemas, then Use Embedded Schema is best
> practice for the Avro Reader. However it is not intuitive that if the same
> schema that is embedded in the file is specified by name (using a schema
> registry) or explicitly via Schema Text, that errors can occur. This has been
> noticed in QueryRecord for example, and the error is also not intuitive or
> descriptive (it is often an ArrayIndexOutOfBoundsException).
> To provide a better user experience, it would be an improvement for
> AvroReader to be able to successfully process Avro files with embedded
> schemas, even when the Schema Access Strategy is not "Use Embedded Schema".
> Of course, the explicit schema would have to match the embedded schema, or an
> error would be reported (and rightfully so).
