[jira] [Commented] (BEAM-1190) FileBasedSource should ignore files that matched the glob but don't exist

    [ https://issues.apache.org/jira/browse/BEAM-1190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16111508#comment-16111508 ] 

Eugene Kirpichov commented on BEAM-1190:
----------------------------------------

GCS object listing is strongly consistent now. However the issue still applies for other filesystems like S3.

> We should, after globbing the files in FileBasedSource, individually stat every file and remove those that don't exist, to account for the possibility that glob yielded non-existing files due to eventual consistency.
