oleg-zinovev commented on issue #1836: DRILL-7156: empty parquet files support URL: https://github.com/apache/drill/pull/1836#issuecomment-520807005 > Please provide example... I added a test TestParquetWriterEmptyFiles#testWriteEmptySchemaChange. As you can see, there is no "a" field in the written schema. Probably, it would be correct to write schema for all empty scans, but it will lead to writing "garbage" empty parquet files, if the scan with data is at the end of batch.
