Hi,

I am new in the field of Big data and Hadoop and was going through a study material where it was written that " There are different daemons in yarn", but they did not mentioned what are they? So can anyone put up an answer to explain this?

Hi,

The different Daemons in YARN are:-

Resources Manager:- Runs on a master daemon and manages the resource allocation in the cluster.

Node Manager:- They run on the slave daemons and are responsible for the execution of a task on every single Data Node.

Application Master:- Manages the user job life cycle and resource needs of individual applications. It works along with the Node Manager and monitors the execution of tasks.
