Q7 Single choice

Each node in your Hadoop cluster, running YARN, has 64 GB memory and 24 cores. Your yarn-site.xml has the following configuration:

<property>
<name>yarn.nodemanager.resource.memory-mb</name>
<value>32768</value>
</property>
<property>
<name>yarn.nodemanager.resource.cpu-vcores</name>
<value>23</value>
</property>

You want YARN to launch no more than 16 containers per node.

What should you do?

A
No action is needed: YARN's dynamic resource allocation automatically optimizes the node memory and cores
B
Modify yarn-site.xml with the following property:
<name>yarn.nodemanager.resource.cpu-vcores</name>
<value>16</value>
C
Modify yarn-site.xml with the following property:
<name>yarn.scheduler.minimum-allocation-mb</name>
<value>2048</value>
D
Modify yarn-site.xml with the following property:
<name>yarn.scheduler.minimum-allocation-mb</name>
<value>4096</value>
