Review comment:
actually, we do support multi-levels other than 3, let me remove this.

> Find the entities from the system catalog which views have TTLs defined on
> them. Spawn an MR job, whose splitter will create a map task. The mapper
> issues “select count(1) from the entity and Inject TTL attributes and Delete
> Hint during Map task. Since the current Phoniex MR framework doesn't support
> this feature, PhoenixMultiViewReader, PhoenixMultiViewInputSplit,
> PhoenixMultiViewInputFormat, and a few MR related util classes need to
> implement.
