Description

HADOOP-7633 made hdfs, mr and security audit logging on by default (INFO level) in log4j.properties used for the packages, this then got copied over to the non-packaging log4j.properties in HADOOP-8216 (which made them consistent).

Seems like we should keep with the v1.x setting which is disabled (WARNING level) by default. There's a performance overhead to audit logging, and HADOOP-7633 provided not rationale (just "We should add the audit logs as part of default confs") as to why they were enabled for the packages.
