Subject [jira] [Commented] (HDFS-12772) RBF: Track Router states
Date Tue, 14 Nov 2017 01:34:00 GMT

Íñigo Goiri commented on HDFS-12772:
------------------------------------

Thanks [~hanishakoneru], as I mentioned this was longer than I expected :)
Not sure, where to draw the line though.
The 3 parts could be:
# Adding {{RouterState}} to the State Store
# Router heartbeating of this state
# Exposing this in the UI

I'd say 1 is the largest one.
Not sure if 2 and 3 in the same patch make sense; at the same time individually they might
be really small.

> To monitor the state of the cluster, we should track the state of the routers. This should
be exposed in the UI.
