[jira] [Created] (HDFS-4683) Per directory trash settings / trash override

John Vines created HDFS-4683:
--------------------------------

             Summary: Per directory trash settings / trash override
                 Key: HDFS-4683
                 URL: https://issues.apache.org/jira/browse/HDFS-4683
             Project: Hadoop HDFS
          Issue Type: Improvement
         Environment: Hadoop2
            Reporter: John Vines


With the migration of trash settings to server side, it becomes more complicated for applications built on top of HDFS to properly deal with their trash. Applications like HBase and Accumulo already have a fair amount of trash management, adding the HDFS Trash will simply put more stress on DFS. But fully disabling the trash is overkill, as there still may be use for it in other uses of hadoop.

I would like to request either:
A. per directory or user trash settings, so that applications which work in a specific directory or use a specific user can continue to ignore the trash.
B. An updated DistributedFileSystem delete() call which allows you to force ignoring the trash. I'm not sure how feasible this is due to the FileSystem API, but it may be possible.
