In YARN, what is a container?

A virtual machine running on each node

A network partition for data transfer

A unit of resource allocation that includes CPU, memory, and other resources

What is the primary responsibility of the ApplicationMaster in YARN?

To negotiate resources and monitor the progress of the application

To manage the storage of application data

To manage the cluster's overall resource allocation

To execute the map and reduce tasks

A YARN cluster is running a mix of short and long jobs. The administrator wants to ensure that no single user can monopolize the cluster. The administrator decides to use the Fair Scheduler. What is the primary mechanism the Fair Scheduler uses to prevent a single user from monopolizing resources?

It assigns each user a fixed queue with a hard capacity limit that cannot be exceeded.

It requires all jobs to specify a maximum resource limit at submission time.

It dynamically balances resources among running jobs so that each job gets roughly the same share of resources over time.

It processes jobs in strict FIFO order, ensuring that early-submitted jobs finish before later ones start.

In the YARN workflow, what happens after the ApplicationMaster is launched?

The ApplicationMaster registers with the ResourceManager and requests containers

The client directly starts tasks on nodes

The ResourceManager executes the tasks
