Subject Re: How do I set the log level?

Ah, figured it out (writing for posterity).

Daemons expose a log level set/get gui at /logLevel:


You enter the full qualfiied class name to retrieve the current level
or set a given level.

Also, can be done through "bin/yarn daemonlog":

java org.apache.hadoop.log.LogLevel -getlevel <host:port> <name>
java org.apache.hadoop.log.LogLevel -setlevel <host:port> <name> <level>
