Chris Nauroth commented on HDFS-4776:
-------------------------------------

+1 for the patch.  It looks like a clean backport.

     [exec]     -1 tests included.  The patch doesn't appear to include any new or modified
tests.
     [exec]                         Please justify why no tests are needed for this patch.

I tested the patch manually by building the distro and running 1 each of NN, DN, and 2NN.
 I accessed the 2NN's web UI and ran some file system operations.  I saw the 2NN checkpoint
successfully, and I verified that the web UI updated the displayed information about the last
checkpoint.

Thanks for doing the backport, Nicholas!
