> In Karaf, most of the code is run under the "karaf" user. When a user ssh into Karaf,
commands will be executed under that user.
> Deploying hadoop inside Karaf requires that the authenticated Subject has the required
hadoop principals set, which forces the reconfiguration of the whole security layer, even
at dev time.
> My patch proposes the introduction of a new configuration property {{hadoop.security.force.login.user}}
which if set to true (it would default to false to keep the current behavior), would force
the use of the login user instead of using the authenticated subject (which is what happen
when there's no authenticated subject at all).  This greatly simplifies the use of hadoop
in such environments where security isn't really needed (at dev time).
