Description

Currently the BlockCollection interface returns BlockInfoContiguous objects in multiple calls.

In order to decouple block manager and the namespace, the interface should return the Block instead of BlockInfoContiguous objects, where the latter contain information like the locations of DN.

This jira proposes to clean up the interface and to return the Block objects directly.
