I was facing this issue SPARK-24295 so I was looking into commit. I have two queries.
1. if we ignore sink metadata then we may face correct files/duplicate file issue as mentioned by @tdas in this mail chain [http://mail-archives.apache.org/mod_mbox/spark-user/201706.mbox/%3CCA+AHuKmDDRCr4ZjvXOaaX+9QjLfMhF7Xy1qyUL3VH2Q3ziAQwg@mail.gmail.com%3E](url)
2. will CompactibleFileStreamLog.compact fail because there will not be any batchid to compact?
