> 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.
