Steve Loughran commented on HADOOP-13032:
-----------------------------------------
Like you say, this is going to be pretty significant. It's changing a public
API, no?
I'm not worried about FS implementations breaking in the move to 3.x; wondering
if we have to care about client-side code?
Like your adoption of lambda expressions BTW.

> [HADOOP-13065] added a new interface for retrieving FS and FC Statistics.
> This jira is to track the effort of moving the {{Statistics}} class out of
> {{FileSystem}}, and make it use that new interface.
> We should keep the thread local implementation. Benefits are:
> # they could be used in both {{FileContext}} and {{FileSystem}}
> # unified stats data structure
> # shorter source code
> Please note this will be an backwards-incompatible change.
