------------
No new tests added with this patch, as the patch is specific to Keberos and the
current unit test framework doesn't extend itself to test this. However the
patch has been tested manually.
A keytab file for the proxy user was created and the principal in keytab file
is configured as proxy user in the Namenode configuration[core-site.xml]
(hadoop.proxyuser.proxy.users, hadoop.proxyuser.proxy.ip-addresses). Ip address
configured in Namenode core-site.xml is that of the server where hdfsproxy is
setup to run and the proxy user is same as the user in the keytab file. With
this, doAs requests are successful and the requests are able to retrieve files
only readable by the requesting user or the users' group.
> Allow HDFSProxy to impersonate the real user while processing user request
