A large global enterprise customer has a Big Data environment set up on Hadoop. After a year in operation they are now looking to extend access to multiple functions that will need different views into different aspects/portions of the data.

As you consider these requirements, which of the following statements is TRUE and also applies to the scenario?
A . Hadoop does not support multi tenancy but can easily scale to support this by replicating data to new clusters with commodity hardware.
B . Hadoop can support multi tenancy but only if YARN is used, so if not already used, the customer will need to upgrade to a YARN supported version.
C . Virtualization methods can be used to support multi-tenancy on Hadoop because one can easily replicate to additional cluster whenever there is a need.
D . Hadoop can support multi tenancy by using a cluster file system for storage, allowing all nodes to access the data.

Answer: D
