-----------------------------------
Summary: Audit logging should be disabled by default
Key: HADOOP-8316
URL: https://issues.apache.org/jira/browse/HADOOP-8316
Project: Hadoop Common
Issue Type: Bug
Components: conf
Affects Versions: 2.0.0
Reporter: Eli Collins
Assignee: Eli Collins
HADOOP-7633 made hdfs 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. Note that as
of HADOOP-8224 you'll be able to configure this.
