Alexander Preuss commented on FLINK-26322:
------------------------------------------

I tested the FileSink's compaction and here are my observations for the scenarios:
 # Working as expected
 # Working as expected
 # Throws  java.lang.IllegalStateException: Illegal committable to compact, pending file is null
 # Does not finish/seems to be stuck. No logs after the job has been submitted
