Description

When starting the NameNode with a German locale (or some other that uses "," as the decimal separator), the web interface (dfshealth.jsp) crashes with a NumberFormatException.

To reproduce:

$ LC_ALL=de_DE bin/start-dfs.sh

Then copy some data to the store so that the percentage of used space is above 0%. Load the web interface in your browser and you'll get a HTTP 500 error message.

The problem is that FsShell gives you a localized number (eg. "0,7") which can't be parsed by Double.parseDouble().
