---------------------------------

             Summary: Append job name (or job id) to temporary directory name 
in FileBasedSink
                 Key: BEAM-8289
                 URL: https://issues.apache.org/jira/browse/BEAM-8289
             Project: Beam
          Issue Type: Bug
          Components: io-java-files
            Reporter: Heejong Lee
            Assignee: Heejong Lee


There was an issue that a temporary directory name is not unique in 
FileBasedSink (https://issues.apache.org/jira/browse/BEAM-7689) and we've 
changed the naming algorithm from timestamp to UUID. However, it looks like 
UUID is still not enough to distinguish two separate temporary directories from 
different jobs. We may need to put job name or job id to the temporary 
directory name for avoiding future naming collision.
