László Bodor updated TEZ-4434:
------------------------------
    Description: 
Tez depends on log4j v1 transitively through hadoop-common, but log4j2 is also 
present in hadoop's pom. 
In general, we should check what kind of benefits are present with using v2, 
e.g. [async logging|https://logging.apache.org/log4j/2.x/manual/async.html]


> Introduce log4j2
