Cloudera Certified Administrator for Apache Hadoop CDH4 Upgrade Exam (CCAH) Sample Questions:
Question 1
What happens if a Mapper on one node goes into an infinite loop while running a MapReduce job?
A. The Mapper will run indefinitely; the TaskTracker must be restarted to kill it
B. After a period of time, the JobTracker will restart the TaskTracker on the node on which the map task is running
C. After a period of time, the TaskTracker will kill the Map Task.
D. The job will immediately fail.
Question 2
Which two updates occur when a client application opens a stream to begin a file write on a cluster running MapReduce v1 (MRv1)?
A. The change is written to the NameNode disk.
B. Once the write stream closes on the DataNode, the DataNode immediately initiates a black report to the NameNode.
C. The change is written to the edits file.
D. The metadata in RAM on the NameNode is flushed disk.
E. The metadata in RAM on the NameNode is updated.
F. The metadata in the RAM on the NameNode is flushed to disk.
Question 3
You set up the Hadoop cluster using NameNode Federation. One NameNode manages the/users namespace and one NameNode manages the/data namespace. What happens when client tries to write a file to/reports/myreport.txt?
A. The client throws an exception.
B. The file successfully writes to /report/myreport.txt. The metadata for the file is managed by the first NameNode to which the client connects.
C. The file successfully writes to /users/reports/myreports/myreport.txt.
D. The file writes fails silently; no file is written, no error is reported.
Question 4
Identify four characteristics of a 300MB file that has been written to HDFS with block size of 128MB and all other Hadoop defaults unchanged?
A. The third Initial block will be 44 MB
B. The third block will be 64MB
C. Each block will be replicated nine times
D. All three blocks will be 128MB
E. Two of the initial blocks will be 128MB
F. Each block will be replicated three times
G. The file will consume 1152MB of space in the cluster
H. The file will be split into three blocks when initially written into the cluster
Question 5
How does HDFS Federation help HDFS Scale horizontally?
A. HDFS Federation reduces the load on any single NameNode by using the multiple, independent NameNode to manage individual pars of the filesystem namespace.
B. HDFS Federation improves the resiliency of HDFS in the face of network issues by removing the NameNode as a single-point-of-failure.
C. HDFS Federation allows the Standby NameNode to automatically resume the services of an active NameNode.
D. HDFS Federation provides cross-data center (non-local) support for HDFS, allowing a cluster administrator to split the Block Storage outside the local cluster.
