[jira] [Commented] (BEAM-4440) When filesToStage is empty, the DataflowRunner should fail.

    [ https://issues.apache.org/jira/browse/BEAM-4440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17102223#comment-17102223 ] 

Kenneth Knowles commented on BEAM-4440:
---------------------------------------

The title of the bug sounds like it is referring to the entirety of fileToStage. The comment here (which I agree with) is related. If a file is specified, either by specific name or glob emptiness, we should fail.

> Staging no files will not permit any pipeline execution to succeed. This should cause the pipeline to fail before job submission.

> In general, if any file to stage is specified and expands to no files, this should also be a failure. Specifying a glob that represents no files is almost certainly user error.
