t oo created SPARK-36147:
----------------------------

             Summary: [SQL] - log level should be warning if files not found in BasicWriteStatsTracker
                 Key: SPARK-36147
                 URL: https://issues.apache.org/jira/browse/SPARK-36147
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.2
            Reporter: t oo


This log should at least be WARN not INFO (in [org/apache/spark/sql/execution/datasources/BasicWriteStatsTracker.scala|https://github.com/apache/spark/pull/33332#diff-2a68131bcf611ecf51956d2ba63e8a9ee6d1d20a7a54eeeb4195a4ba1d365134] )

 

"Expected $numSubmittedFiles files, but only saw $numFiles."

 

in my case (using s3) just yesterday, the file was never created and job didn't fail! so I ended up with silently missing data
