In the PR, I propose move out creation of
AvroOptionfromAvroPartitionReaderFactory.buildReader, and create it earlier inAvroScan.createReaderFactory.Why are the changes needed?
AvroOptionsfrom a map of Avro options and Hadoop conf per each partition.AvroOptionsis built only once at the driver side, we could output warnings while parsing Avro options and don't worry about noisiness of the warnings.Does this PR introduce any user-facing change?
No
