Hi, dear all: I might find a spelling error in "http://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/CommandsManual.html"; here is the details: Administration Commands Commands useful for administrators of a hadoop cluster. daemonlog Usage: hadoop daemonlog -getlevel <host:port> <classname> [-protocol (http|https)] hdoop daemonlog -setlevel <host:port> <classname> <level> [-protocol (http|https)] the second line "hdoop" ,mayebe "hadoop" is correct ?
Best Wishes ~
