Matthias commented on FLINK-20258:
----------------------------------
I forwarded the memory-related parameter values using bytes for precision
reasons (and because it is done in the same way for the TaskManager).
[~vthinkxie] and I discussed having the conversion being done in the frontend
vs the backend. We decided to do the conversion into human-readable units in
the UI instead of using {{MemorySize#toHumanReadableString}} in the backend. I
wanted to document in the comment above that I verified [~vthinkxie]'s
requirement that the used unit provided by the {{/jobmanager/config}} endpoint
is stable.
> Configured memory sizes on the JM metrics page should be displayed with
> proper units.
