Sometimes users can get non-hudi files mixed in Hudi table

How could this happen?

[CTTY]

Hi @danny0405 , this would happen when some users accidently copy files to their table location or writer is not correctly set up like they forgot to use HoodieSparkSessionExtension. Either way I think we need to report this error better to help people understand the issue
