> 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.
