[~HuafengWang], [~drankye], was the intent of this patch to log all IOExceptions as well, since that is not what most FSNameSystem calls do at the moment. My understanding is have audit logs for AccessControlException (allowed=false) and in successful cases (allowed=true) since logging allowed=false in the case of IOException could be misleading. Let me know your thoughts on this and I will rebase my patch for HDFS-11246 accordingly. Thanks!

P.S. The commit has the wrong JIRA number in it (points to HDFS-12306).

> These three FSNameSystem operations do not yet record audit logs. I am not sure how useful these audit logs would be, but thought I should file them so that they don't get dropped if they turn out to be needed.
