If you did not use –skipTrash, the file should be in your trash. Refer: http://hadoop.apache.org/common/docs/current/hdfs_design.html#File+Deletes+and+Undeletes for more information.

Do you have snapshots?  Or other forms of backup?  Otherwise you are
basically out of luck.

It might be too late now since this is several hours ago, but you might
have been able to recover some of it by shutting down the DNs, and
restoring a previous fsimage (you *are* checkpointing, aren't you?).
