A) Nn01 is fenced, and nn02 becomes the active NameNode
B) Nn01 becomes the standby NameNode and nn02 becomes the active NameNode
C) nn02 becomes the standby NameNode and nn02 becomes the active NameNode
D) Nn01 is fenced, and nn01 becomes the active NameNode

2. 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?
