mapred-site.xml:
<name>mapreduce.job.maps</name>
<value>2</value>
B) Configure the ResourceManager hostname and enable node services on YARN by
setting the following property in yarn-site.xml:
<name>yarn.resourcemanager.hostname</name>
<value>your_responseManager_hostname</value>
C) Configure a default scheduler to run on YARN by setting the following property in
sapred-site.xml:
<name>mapreduce.jobtracker.taskScheduler</name>
<value>org.apache.hadoop.mapred.JobQueueTaskScheduler</value>
D) Configure MapReduce as a framework running on YARN by setting the following
property in mapred-site.xml:
<name>mapreduce.framework.name</name>
<value>yarn</value>
E) Configure the NodeManager to enable MapReduce services on YARN by adding
following property in yarn-site.xml:
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
F) Configure the NodeManager hostname and enable services on YARN by setting the
following property in yarn-site.xml:
<name>yarn.nodemanager.hostname</name>
<value>your_nodeManager_hostname</value>

2. Your cluster's mapped-site.xml includes the following parameters
<name>mapreduce.map.memory.mb</name>
<value>4096<value/>
<name>mapreduce.reduce.memory,mb</name>
<value>8192</value>
And your cluster's yarn-site.xml includes the following parameters
<name>yarn.nodemanager/vmen-pmem-ratio</name>
<value>2.1</value>
What is the maximum amount of virtual memory allocated for each map before YARN will kill its Container?

A) 24.6 GB
B) 17.2 GB
C) 4 GB
D) 8.2 GB

3. You are running a Hadoop cluster with MapReduce version 2 (MRv2) on YARN. You consistently see that MapReduce map tasks on your cluster are running slowly because of excessive garbage collection of JVM, how do you increase JVM heap property to 3GB to optimize performance?

B) Mapreduce.map.java.opts=-Xms3072m
C) Yarn.application.child.java.opts-Xax3072m
D) Yarn.application.child.java.opts=-3072m

4. You are upgrading a Hadoop cluster from HDFS and MapReduce version 1 (MRv1) to one running HDFS and MapReduce version 2 (MRv2) on YARN. You want to set and enforce a block of 128MB for all new files written to the cluster after the upgrade. What should you do?

A) You cannot enforce this, since client code can always override this value.
