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

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?

Which three basic configuration parameters must you set to migrate your cluster from
MapReduce 1 (MRv1) to MapReduce V2 (MRv2)?

You need to analyze 60,000,000 images stored in JPEG format, each of which is
approximately 25 KB. Because you Hadoop cluster isn’t optimized for storing and
processing many small files, you decide to do the following actions: 1. Group the individual
images into a set of larger files 2. Use the set of larger files as input for a MapReduce job
that processes them directly with python using Hadoop streaming. Which data serialization
system gives the flexibility to do this?

Identify two features/issues that YARN is designated to address:

Which YARN daemon or service monitors a Controller’s per-application resource using
(e.g., memory CPU)?

Which is the default scheduler in YARN?

Which YARN process run as “container 0” of a submitted job and is responsible for resource
qrequests?

Which scheduler would you deploy to ensure that your cluster allows short jobs to finish
within a reasonable time without starting long-running jobs?

Your cluster is configured with HDFS and MapReduce version 2 (MRv2) on YARN. What is
the result when you execute: hadoop jar SampleJar MyClass on a client machine?
