Íñigo Goiri commented on YARN-8504:

Yes, same thing for NodesPage very easy to break.
Ideally, we should even check that the type is the correct; for example if the 
table defines column X as sortable, we should check that it does so.
However, the latter is a little too complex.
At least a basic check that the numbers match should be there.
