Jakob Homan updated HDFS-1033:
------------------------------
Attachment: HDFS-1033.patch
Patch for trunk. Straight forward port of patch, but shouldn't be committed
yet as a couple other patches went in first. This patch is smaller than the
Y20 patch as a bunch of changes to the keys that had been in this one were
leapfrogged by HDFS-1163, it appears.
> In secure clusters, NN and SNN should verify that the remote principal during
> image and edits transfer

> Currently anyone can connect and download image/edits from Namenode. In a
> secure cluster we can verify the identity of the principal making the
> request; we should disallow requests from anyone except the NN and SNN
> principals (and their hosts due to the lousy KerbSSL limitation).
