> I would like to switch on the debug log level of the namenode 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.
