Arpit Gupta reopened HDFS-3727:
-------------------------------


Can we commit this to branch 1.1 so that the next release can pull it in.

Also a couple of unused imports got left in the class after this patch.

> When performing a checkpoint with security enabled, the NN will attempt to relogin from its keytab before making an HTTP request back to the 2NN to fetch the newly-merged image. However, it always attempts to log in using the KSSL principal, even if SPNEGO is configured to be used.
