Description

Sometimes, some non-IOException prevents User.getCurrent() to get a username. It makes it impossible to create a HConnection. We should catch all exception here:

      try {
        User currentUser = User.getCurrent();
        if (currentUser != null) {
          username = currentUser.getName();
        }
      } catch (IOException ioe) {
        LOG.warn("Error obtaining current user, skipping username in HConnectionKey",
            ioe);
      }

Not just IOException, so that client can move forward.
