Resolution: Duplicate
> Allow for Creating Temporary Files
> ----------------------------------
>
> Key: HDFS-13988
> URL: https://issues.apache.org/jira/browse/HDFS-13988
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: hdfs, hdfs-client
> Affects Versions: 3.2.0
> Reporter: BELUGA BEHR
> Priority: Major
>
> Allow clients to create temporary files in HDFS.
> {code:java|title=FileSystem.java}
> public FSDataOutputStreamBuilder createFile(Path path);
> public FSDataOutputStreamBuilder appendFile(Path path);
> // New feature
> public FSDataOutputStreamBuilder createTempFile(Path path, TimeUnit unit,
> long ttl);
> {code}
> This would register the file with the NameNode to have a TTL. The NameNode
> would be responsible for deleting the files after some custom TTL. This
> would be helpful in the case that a MapReduce (or Spark) job fails during
> execution and does not properly clean up after itself.
