> We have startup timestamp for RM already, but don't for NM.
> Sometimes cluster operator modified configuration of all nodes and kicked off command
to restart all NMs.  He found out it's hard for him to check whether all NMs are restarted.
 Actually there's always some NMs didn't restart as he expected, which leads to some error
later due to inconsistent configuration.
> If we have startup timestamp for NM,  the operator could easily fetch it via NM webservice
and find out which NM didn't restart, and take mannaul action for it.
