Summary
recordTypedatasource option case-insensitively during schema inference, reads, and writes.Exampledefault.ByteArrayregression test using the lower-casedrecordtypekey.Motivation
Spark datasource option keys are case-insensitive, and newer Spark runtimes can pass normalized lower-case keys to V1
FileFormatimplementations. The connector previously looked up only the exactrecordTypespelling, so a suppliedrecordtype=ByteArrayoption silently fell back toExample.Testing
