What does CDH packaging do on install to facilitate Kerberos security setup?

A. Automatically configures permissions for log files at and MAPRED_LOG_DIR/userlogs

B. Creates users for hdfs and mapreduce to facilitate role assignment

C. Creates directories for temp, hdfs, and mapreduce with the correct permissions

You want to understand more about how users browse your public website. For example, you want to know which pages they visit prior to placing an order. You have a server farm of 200 web servers hosting your website. Which is the most efficient process to gather these web server across logs into your Hadoop cluster analysis?

A. Sample the web server logs web servers and copy them into HDFS using curl

B. Ingest the server web logs into HDFS using Flume

C. Channel these clickstreams into Hadoop using Hadoop Streaming

D. Import all user clicks from your OLTP databases into Hadoop using Sqoop

E. Write a MapReeeduce job with the web servers for mappers and the Hadoop cluster nodes for reducers

You are working on a project where you need to chain together MapReduce, Pig jobs. You also need the ability to use forks, decision points, and path joins. Which ecosystem project should you use to perform these actions?

A. Oozie

B. ZooKeeper

C. HBase

D. Sqoop

E. HUE

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)

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
