Cloudera CCA-500 Question Answer

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

yarn.nodemanager.resource.memory-mb

32768

yarn.nodemanager.resource.cpu-vcores

You want YARN to launch no more than 16 containers per node. What should you do?

Modify yarn-site.xml with the following property:

yarn.scheduler.minimum-allocation-mb

2048

Modify yarn-sites.xml with the following property:

yarn.scheduler.minimum-allocation-mb

4096

Modify yarn-site.xml with the following property:

yarn.nodemanager.resource.cpu-vccores

No action is needed: YARN’s dynamic resource allocation automatically optimizes the node memory and cores
