Description

The hadoop fs -get command always shows this warning:

$ hadoop fs -get /data/schemas/sfdc/BusinessHours-2014-12-09.avsc
15/04/06 06:22:19 WARN hdfs.DFSClient: DFSInputStream has been closed already

This was introduced by HDFS-7494. The easiest thing is to just remove the warning from the code.
