hi,

 

I am planning CCDH and require few details on the same. Is the test completely multiple choice or expected to write code also?

 

The 4th secion in the study guide is also not clear:

 

4. Querying Objectives

  • Write a MapReduce job to implement a HiveQL statement.
  • Write a MapReduce job to query data stored in HDFS.

 

What exactly "write a maprreduce job to implement a HiveQL statement" mean? do we have to write MR code which is quivalent to HiveQL statement like select * from table?
