We have been running a few Routers without stopping for a couple months and the
memory footprint was growing constantly.
We added a cache cleaner that periodically removed the unused resolutions.

[jira] [Commented] (HDFS-12775) [READ] Fix reporting of Provided volumes

Íñigo Goiri commented on HDFS-12775:
[~virajith], thanks for working on this.
I think separating the provided statistics is the way to go, the semantics
might get confusing otherwise.
Given that the Namenode UI already has a section for the Storage Type, there is
no need on trying to aggregate the provided capacity into the regular HDFS
capacity.
A couple minor comments:
* Is the TODO in the patch needed?
* Can you post a screenshot with the new information?

> HDFS-11156 was reverted because the implementation was non optimal, based on
> the suggestion from [~shahrs87], we should avoid creating a dfs client to get
> block locations because that create extra RPC call. Instead we should use
