Our resource manager UI (Ambari Home -> Yarn Links -> More... -> ResourceManagerUI) now defaults to always sort in such a way that jobs from January 5th are always on top. I have to click the "start time" header twice to get jobs sorted by most recent start time, which is the expected default - and how it has worked for last 2 years.
It persists even after clearing cache / deleting cookies / etc.
I even re-installed firefox and still get the same behavior.
Does anyone know why this is hapening or how to fix it?
