}

Example 4 with LoggerContext

use of org.apache.logging.log4j.core.LoggerContext in project hive by apache.

the class TestLog4j2Appenders method setup.

@Before
public void setup() {
    // programmatically set root logger level to INFO. By default if log4j2-test.properties is not
    // available root logger will use ERROR log level
    LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
    Configuration config = ctx.getConfiguration();
    LoggerConfig loggerConfig = config.getLoggerConfig(LogManager.ROOT_LOGGER_NAME);
    loggerConfig.setLevel(Level.INFO);
