Your cluster is running Map v1 (MRv1), with default replication set to 3, and a cluster blocks
64MB. Identify which best describes the file read process when a Client application connects into
the cluster and requests a 50MB file?

How must you format the underlying filesystem of your Hadoop cluster’s slave nodes running on
Linux?

Your developers request that you enable them to use Hive on your Hadoop cluster. What do install
and/or configure?

You’ve configured your cluster with HDFS Federation. One NameNode manages the /data
namesapace and another Name/Node manages the /reports namespace. How do you configure a
client machine to access both the /data and the /reports directories on the cluster?

Your cluster implements HDFS High Availability (HA). You two NameNodes are named nn01 and
nn02. What occurs when you execute the command:
Hdfs haadmin -failover nn01 nn02

What metadata is stored on a DataNode when a block is written to it?

Your Hadoop cluster contains nodes in three racks. Choose which scenario results if you leave the
dfs.hosts property in the NameNode’s configuration file empty (blank)?

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

Compare the hardware requirements of the NameNode with that of the DataNodes in a Hadoop
cluster running MapReduce v1 (MRv1):

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