> In our cluster setup, the YARN web UI always shows progress bars at 100% (see
> screenshot, progress of the reduce step is roughly at 32.82%). I opened the
> HTML source code to check (also see screenshot), and it seems the problem is
> that it uses a comma as decimal mark, where most browsers expect a dot for
> floating-point numbers. This could possibly be due to localized number
> formatting being used in the wrong place, which would also explain why this
> bug is not always visible.
