Hello,  we have 5.11 cluster installed for testing, 2 master nodes, 4 slave nodes, and 1 management node. now we want to enable the audit logging without using Navigator.    I have some questions here 1. we have CM installed, can I use log4j.properties to enable the audit logging?     I read some posts like this:     https://community.cloudera.com/t5/Cloudera-Manager-Installation/What-is-the-Path-of-hdfs-site-xml-core-xml/m-p/15210#M1787  it said that the actual configuration has non-standard location. So my understanding is no matter what I changed on the configruation location(e.g. /etc/hadoop/conf/.....), it won't work. And I should use the snippet to do the configuration.     2. and I read another posts here: http://community.cloudera.com/t5/Cloudera-Manager-Installation/Audit-trail-for-HDFS-data-use/m-p/50428/highlight/true#M9405 looks like I can use log4j.properties to do the audit logging.   I am a little bit confused, how can I enable audit logging without Nav?   Thanks in advance!       ...
