Can NMs communicate among themselves?

Hi,

The communication in YARN is b/w RM-NM or AM-RM from what I know.
Can Node Managers talk to each other? If so, how?

Also what protocol or communication model does hadoop follow?

Thanks,

You would best bake this into your YARN application. Inter process Communication can be implemented in the container. 

You should take a look at the weave framework as well.

Hi Sandy,

Thank you so much for the immediate response.

Is there a way to make it happen? Any suggestions will be greatly
appreciated.

Also, can you tell me how any communication happens in the cluster, be it
between RM and nodes or any scenario?

Thanks,

Hi Sandy,

Thank you so much for the immediate response.

Is there a way to make it happen? Any suggestions will be greatly
appreciated.

Also, can you tell me how any communication happens in the cluster, be it
between RM and nodes or any scenario?

Thanks,

Hi Santosh,

NodeManagers do not communicate with each other in YARN.
