Xiaoyu Yao commented on HDFS-13207:
-----------------------------------
Thanks [~bharatviswa] for reporting the issue and posting the patch. I just
have few questions:
1. In the patch, we added the block pool used per datanode. Should we add
"block pool used" to the summary portion before the "Live datanodes" as well?
2. If there are multiple namespaces and block pools, is it possible to separate
the usage of different block pool?
3. Should we default to turn this off and show the "block pool used" only when
federation is configured or a CLI switch like "-blockPoolUsed" is provided?

> Add block pool used for dfsadmin -report command.
> This will be helpful on a federated cluster to know DFS used by a particular
> namespace.
>
> On a non-federated cluster, blockPoolUsed and DFSUsed will be shown as same.
