Xuan Gong commented on YARN-1640:
---------------------------------
In this patch, we create an rmloginUGI to save the UGI which is used to
doSecureLogin, and use it start active services. In secure model, the
rmLoginUGI will be the loginUGI, and in non-secure model, it will be
currentUGI.
> Manual Failover does not work in secure clusters
