Question-8: Can you please map the following (Keeping Cloudera Manager concepts in mind)

Deployment

Rack

Role Group

Dynamic Resource Pool

For Cloudera Manager, it represents the configuration of Cloudera Manager and all the clusters it manages.

Represents a physical entity which contains a set of physical hosts and typically served by the same switch

This is a set of configuration properties for a set of Role instances.

It is a named configuration of resources and a policy for scheduling the resources among YARN applications

Answer:

Exp:

Role Group

• This is a set of configuration properties for a set of Role instances.

Host

• This represents a physical or virtual machine, that run role instances i.e. in case of HDFS, it could be either NameNode or DataNode Role instance.
• One host can belong to only one cluster.

Host Template

• A set of role groups in Cloudera Manager. When a template is applied to a host, a role instance from each role group is created and assigned to that host.

Rack

• Rack represents a physical entity which contains a set of physical hosts and typically served by the same switch.

A Deployment

• For Cloudera Manager, a deployment represents the configuration of Cloudera Manager and all the clusters it manages.

Dynamic Resource Pool

• In Cloudera Manager, it is a named configuration of resources and a policy for scheduling the resources among YARN applications or Impala queries running in the pool.
