Is it possible to turn off all the Hadoop logs simultaneously? In my unit
tests, I don’t want to see the myriad “INFO” logs spewed out by various Hadoop
components. I’m using:
((Log4JLogger) DataNode.LOG).getLogger().setLevel(Level.OFF);
((Log4JLogger) LeaseManager.LOG).getLogger().setLevel(Level.OFF);
((Log4JLogger) FSNamesystem.LOG).getLogger().setLevel(Level.OFF);
((Log4JLogger) DFSClient.LOG).getLogger().setLevel(Level.OFF);
((Log4JLogger) Storage.LOG).getLogger().setLevel(Level.OFF);
But I’m still missing some loggers...
you need a log4j.properties file on the CP that doesn't log so much. I
do this by
-removing /logj4.properties from the Hadoop jars in our (private) jar
repository
-having custom log4.properties files in the test/ source trees
You could also start junit with the right log4j properties to point it
at a custom log4j file. I forget what that property is.
