Subject [jira] Commented: (HADOOP-3336) Direct a subset of namenode RPC events for audit logging
Date Mon, 12 May 2008 05:41:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12595976#action_12595976
] 

dhruba borthakur commented on HADOOP-3336:
------------------------------------------

The current patch assumes that the first column is the ugi, the second column is the permissions,
the third column is the command, etc,etc. We can make the format a wee-bit forward compatible
if we have it of the form

"ugi=xxx\tperm=xxx\tcmd=xxx"

Then, an application parsing this log output can determine whether the column it is looking
for exists or not.
