Giovanni Matteo Fumarola commented on HDFS-12273:
-------------------------------------------------
Thanks [~elgoiri] for the patch and the offline demo. I have few NITs.
* In {{DFSConfigKeys}}, can you place the keys before the default configs?
* In {{RouterDFSCluster}}, can you remove the unused functions?
* In {{index.html}}, can you remove the extra comments?
* In {{RouterHttpServer}}, can you remove the unused functions?
* In {{Router.java}}, why is createHttpServer protected?
For the rest the webapp has 6 views:
* An overview of the entire federated cluster.
* A detailed view for each subcluster.
* A detailed view of every datanodes.
* A detailed view of the mount tables.
* And the common utilities.
During the demo, I noticed that it may take long to load the pages if a
subcluster(s) is(are) down. Can we add a timeout for the calls that can go in
timeout?
