Subject [jira] [Commented] (YARN-8066) RM/UI2: doughnut chart mis-rendering
Date Sat, 24 Mar 2018 11:15:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-8066?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16412532#comment-16412532
] 

Sreenath Somarajapuram commented on YARN-8066:
----------------------------------------------

The issue was reproducible on Chrome/Chromium browsers in the Debian OS. It was because arcs
with value 0 were getting rendered as one big white circle!
Will attach a patch shortly that fixes the same by controlling the visibility of such arcs.

> * when there are 2 subqueues to the root (llap and default); 
> * the llap queue is running 1 application
> * there are no other active application
> the doughtut chart is rendered incorrectly...like something have eaten some part of it....
> the same thing can be observed when there are other applications are active while watching
the animation during refresh - in that case the incorrect drawing appears a number of time
during animation - but at the end it stabilizes as a correct..
