Hi, I am trying to change the log level of a MR job, I used the following command : hadoop jar appMR.jar MainMR -Dmapreduce.map.log.level=DEBUG <args...> but the -Dmapreduce.map.log.level=DEBUG goes as the first argument to the job. Is there any way to do this only for specific MR jobs without changes the level in the log4j properties file ?

I have two boxes to install Cloudera Management Services. How do you recommend to split the services into the two boxes: The services are: Service Monitor, Activity Monitor, Host monitor, Reports Manager, Event Server, Alert Publisher.
