> The temp directory in FileBasedSink consists of  output + ".temp-beam-" + 
> [UUID.randomUUID()|[https://github.com/apache/beam/blob/v2.14.0/sdks/java/core/src/main/java/org/apache/beam/sdk/io/FileBasedSink.java#L521]].
> By the way, the part of  ".temp-beam-" + UUID.randomUUID()" is fixed when the 
> pipeline is uploaded as Dataflow template, and all the jobs created from the 
> Dataflow template use the same temp_directory, if their output directories 
> are the same.
> This may cause a job deletes temp files generated by another job when the 
> outputs of concurrent template jobs have the same directory (e.g. 
> gs://df-job/output/job1.out and gs://df-job/output/job2.out)  
> It looks like 
> [BigQueryIO|[https://github.com/apache/beam/blob/v2.22.0/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQueryIO.java#L1075-L1163]]
>  creates a BQ job id at execution time in the case of Dataflow template. Can 
> we make a similar fix for FileBasedSink?
