Description
Setting System property "IGNITE_CONSOLE_APPENDER" to true will set rootLogger level to OFF that can be unexpectedly as well.
See http://apache-ignite-users.70518.x6.nabble.com/Logging-ignite-log4j-jar-td11400.html
Seems, we should check if there is no other loggers configured which can inherits rootLogger logging level before raising level or turning rootLogger off.
