Question about YARN NodeManager and ApplicationMaster failures

Sadystio Ilmatunt
Hello,

I have some questions regarding failure of NodeManager and Application Master.
What happens if NodeManager which is running on the same node as
Application Master fails?
Does Application Master fail as well?

Also How is Application Master failure handled with respect to its
(child) container?
Do these containers fail too?
If Yes, is there a way these containers can be assigned to new
instance of application master that might come up on some other node?
