Subject [jira] [Commented] (HDFS-12772) RBF: Track Router states
Date Fri, 03 Nov 2017 20:37:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16238318#comment-16238318

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

Currently it has:
* Router state (including State Store interface).
* UI changes with the Routers and their states (including metrics).
* Router safe mode. When the Router cannot reach the State Store it goes into a safe mode
where it doesn't serve write requests. It also happens at startup.
This is a little longer than I expected, I can split it if so.

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