Duo Zhang commented on LOG4J2-3394:
-----------------------------------
The log4j2.properties is the configuration file I used, and log4j2.err is what
I got on stderr.

This is the error, it seems that in log4j2 we do not support variable lookup
when configuring rootLogger directly in properties file? What I used to
configure rootLogger is
{noformat}
rootLogger = ${sys:hbase.root.logger:-INFO,console}
{noformat}
For security logger, it is fine, as I just put the level and appender directly.
{noformat}
logger.SecurityLogger.name = SecurityLogger
logger.SecurityLogger = INFO,RFAS
logger.SecurityLogger.additivity = false
{noformat}
Checked classpath, I have the newest snapshot log4j2 jars.
