[jira] [Created] (SPARK-29999) Writing empty partition via DSv2 implementation of FileStreamSink throws FileNotFoundException

Jungtaek Lim created SPARK-29999:
------------------------------------

             Summary: Writing empty partition via DSv2 implementation of FileStreamSink throws FileNotFoundException
                 Key: SPARK-29999
                 URL: https://issues.apache.org/jira/browse/SPARK-29999
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Jungtaek Lim


I've discovered this issue while playing with Spark 3.0.0-preview.

Unlike DSv1 version of file sink, DSv2 version of file sink lazily creates output file which leads empty partition to not actually create output file. The behavior itself is not a problem, but while committing task in ManifestFileCommitProtocol, `fs.getFileStatus` throws FileNotFoundException since the file is not created.
