> Currently {{INodeFile}} stores the lists of blocks as references of
> {{BlockInfo}} instead of the block ids. This creates implicit dependency
> between the namespace and the block manager.
> The dependency blocks several recent efforts, such as separating the block
> manager out as a standalone service, moving block information off heap, and
> optimizing the memory usage of block manager.
> This jira proposes to decouple the dependency by storing block ids instead of
> object reference in {{INodeFile}} objects.
