Beibei Zhao created HDFS-16944:
----------------------------------
Summary: Add audit log for RouterAdminServer to save privileged
operation log seperately.
Key: HDFS-16944
URL: https://issues.apache.org/jira/browse/HDFS-16944
Project: Hadoop HDFS
Issue Type: Improvement
Components: federation
Affects Versions: 3.3.4
Reporter: Beibei Zhao
We found that in other components (like namenode in hdfs or resourcemanager in
yarn), debug log and audit log are record seperately.
There are lots of simple logs to help with debug for the developers who can
access to the source code. And there are also audit logs with more detailed
information for privileged operations. In addition, audit logs are always
record to help system admins or users to understand what happened in a real
run.
There is an example in yarn:
{code:java}
try {
// Safety
userUgi = UserGroupInformation.getCurrentUser();
user = userUgi.getShortUserName();
} catch (IOException ie) {
LOG.warn("Unable to get the current user.", ie); // debug log
RMAuditLogger.logFailure(user, AuditConstants.SUBMIT_APP_REQUEST,
ie.getMessage(), "ClientRMService",
"Exception in submitting application", applicationId, callerContext,
submissionContext.getQueue()); // audit log
throw RPCUtil.getRemoteException(ie);
}
{code}
So I suggest to add an audit log for *RouterAdminServer* to save privileged
operation logs seperately.
