Arun Suresh commented on HADOOP-13693:
--------------------------------------

I agree.. the UNAUTHENTICATED line is more noise than signal.. Haven't reviewed the patch
yet but +1 to removing OPTION messages from the log.

> For a successful kms operation, kms-audit.log shows an UNAUTHENTICATED ErrorMsg:'Authentication
required' message before the OK messages. This is expected, and due to the spnego authentication
sequence. (Notice method == {{OPTIONS}})

ErrorMsg:'Authentication required'
> 2016-01-31 21:07:04,911 OK[op=DECRYPT_EEK, key=cloudera, user=cloudera, accessCount=1,
interval=0ms] 
> 2016-01-31 21:07:15,104 OK[op=DECRYPT_EEK, key=cloudera, user=cloudera, accessCount=1,
interval=10193ms] 
> {noformat}
> However, admins/auditors see this and can easily get confused/alerted. We should make
it obvious this is benign.
