> German locale makes NameNode web interface crash
> ------------------------------------------------
>                 Key: HADOOP-2456
>                 URL: https://issues.apache.org/jira/browse/HADOOP-2456
>             Project: Hadoop
>          Issue Type: Bug
>          Components: dfs
>    Affects Versions: 0.15.2
>         Environment: Ubuntu Linux 7.10
>            Reporter: Matthias Friedrich
>            Priority: Minor
>             Fix For: 0.15.2
>         Attachments: namenode-log.txt, number-format-fix.patch
> 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().
