Robert Joseph Evans commented on HDFS-3245:
-------------------------------------------
That makes since.
> Add metrics and web UI for cluster version summary
> --------------------------------------------------
>
> Key: HDFS-3245
> URL: https://issues.apache.org/jira/browse/HDFS-3245
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: name-node
> Affects Versions: 2.0.0
> Reporter: Todd Lipcon
>
> With the introduction of protocol compatibility, once HDFS-2983 is committed,
> we have the possibility that different nodes in a cluster are running
> different software versions. To aid operators, we should add the ability to
> summarize the status of versions in the cluster, so they can easily determine
> whether a rolling upgrade is in progress or if some nodes "missed" an upgrade
> (eg maybe they were out of service when the software was updated)
