> I would like to switch on the debug log level of the namenode (or other
> components) without restarting it. This is needed to analyze a production
> system.
> Can somebody please advice on how to set the loglevel dyncamically on a
> running namenode? I was thinking of enhancing dfsadmin to make an RPC to the
> namenode to set a specified logging level. But the apache common logging APi
> does not export an API to change logging levels.
