----------------------------------

             Summary: [RBF] Make listStatus user root trash dir will return all subclusters trash subdirs if user has any mount points in nameservice.
                 Key: HDFS-17269
                 URL: https://issues.apache.org/jira/browse/HDFS-17269
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: liuguanghua


Same scenario  as HDFS-17263 

If user trash config  fs.trash.checkpoint.interval set to 10min in namenodes, the trash root dir /user/$USER/.Trash/Current will be very 10 min renamed to /user/$USER/.Trash/timestamp .

 

When user  ls  /user/$USER/.Trash, it should be return blow:

/user/$USER/.Trash/Current

/user/$USER/.Trash/timestamp (This is invisible now)

 

So we should  make  that user ls trash root dir can see all trash subdirs in all nameservices which user has any mountpoint in nameservice.
