-----------------------------------

Bulk update: moved all 3.4.0 non-blocker issues, please move back if it is a 
blocker. Retarget 3.5.0.

> Set safemode should not fail if one of the namenode is down.

> When the first namenode (let's say nn0) is down, set safemode command will 
> always fail unless users manually update the configuration. This is 
> distracting when debugging issues.
