Description
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 fail the job when the temporary file is accidentally deleted by another job.
