Multiple Application Masters

[#1]

Hi,

Can Hadoop have multiple application masters on single node. ?

Hi @Rahul Gupta,

Yes, a single node can have more than one application masters when we have several applications running; where each application master belongs to a unique application. None of the application master will be aware of the presence of the other.
