Devaraj Das commented on HADOOP-6656:
-------------------------------------
Well, we started out by trying to make the Refreshable interface work (and Owen
had posted a patch on that on this jira). But we couldn't get it working
reliably, and hence switched to the kinit based renewal. That seems to be
working well so far in our production.
