Question 6

You are planning a Hadoop cluster and considering implementing 10 Gigabit Ethernet as the network fabric. Which workloads benefit the most from faster network fabric?

Options:

A.

When your workload generates a large amount of output data, significantly larger than the amount of intermediate data

B.

When your workload consumes a large amount of input data, relative to the entire capacity if HDFS

C.

When your workload consists of processor-intensive tasks

D.

When your workload generates a large amount of intermediate data, on the order of the input data itself

Question 7

For each YARN job, the Hadoop framework generates task log file. Where are Hadoop task log files stored?

Options:

A.

Cached by the NodeManager managing the job containers, then written to a log directory on the NameNode

Cached in the YARN container running the task, then copied into HDFS on job completion

C.

In HDFS, in the directory of the user who generates the job

D.

On the local disk of the slave mode running the task

Question 8

You have a cluster running with a FIFO scheduler enabled. You submit a large job A to the cluster, which you expect to run for one hour. Then, you submit job B to the cluster, which you expect to run a couple of minutes only.

You submit both jobs with the same priority.

Which two best describes how FIFO Scheduler arbitrates the cluster resources for job and its tasks? (Choose two)

Options:

A.

Because there is a more than a single job on the cluster, the FIFO Scheduler will enforce a limit on the percentage of resources allocated to a particular job at any given time

B.

Tasks are scheduled on the order of their job submission

C.

The order of execution of job may vary

D.

Given job A and submitted in that order, all tasks from job A are guaranteed to finish before all tasks from job B

E.

The FIFO Scheduler will give, on average, and equal share of the cluster resources over the job lifecycle

F.

The FIFO Scheduler will pass an exception back to the client when Job B is submitted, since all slots on the cluster are use
