             Summary: Remove ability for users to easily run the trash emptier
                 Key: HADOOP-8710
                 URL: https://issues.apache.org/jira/browse/HADOOP-8710
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
    Affects Versions: 2.0.0-alpha, 1.0.0
            Reporter: Eli Collins
            Assignee: Eli Collins
         Attachments: hadoop-8710.txt

Users can currently run the emptier via {{hadoop org.apache.hadoop.fs.Trash}}, which seems error prone as there's nothing in that command that suggests it runs the emptier and nothing that asks you before deleting the trash for all users (that the current user is capable of deleting). Given that the trash emptier runs server side (eg on the NN) let's remove the ability to easily run it client side.  Marking as an incompatible change since someone expecting the hadoop command with this class specified to empty trash will no longer be able to (they'll need to create their own class that does this).
