Arun Suresh commented on HADOOP-11176:
--------------------------------------
* The findBugs warnings are actually unrelated to the patch.. they will start
to show up since HADOOP-11178 (which fixes the findBugs exclusion file) is
resolved. They should go away once HADOOP-11122 is fixed and committed
* The release audit warning also looks unrelated
> KMSClientProvider authentication fails when both currentUgi and loginUgi are
> a proxied user

> In a secure environment, with kerberos, when the KMSClientProvider instance
> is created in the context of a proxied user, The initial SPNEGO handshake is
> made with the currentUser (the proxied user) as the Principal.. this will
> fail, since the proxied user is not logged in.
> The handshake must be done using the real user.
