> Sometimes tests (and perhaps other client applications) might need an access to the state
of a block's replica.
> Currently it is accessible through  {{FSDataset}} member of {{DataNode}} class. However,
{{FSDataset}} is an internal matter of {{DataNode}} and shouldn't be available externally.
> This JIRA will provide new getter method which will be returning a copy of a block's
replica instead of a reference to an actual replica.
