Subject [jira] [Created] (HDFS-13045) RBF: Improve error message returned from subcsluter
Date Mon, 22 Jan 2018 22:20:01 GMT
Wei Yan created HDFS-13045:

             Summary: RBF: Improve error message returned from subcsluter
                 Key: HDFS-13045
                 URL: https://issues.apache.org/jira/browse/HDFS-13045
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Wei Yan
            Assignee: Wei Yan

Currently, Router directly returns exception response from subcluster to client, which may
not have the correct error message, especially when the error message containing a path.

One example, we have a mount path "/a/b" mapped to subclusterA's "/c/d". If user1 does a chown operation
on "/a/b", and he doesn't have corresponding privilege, currently the error msg looks like
"Permission denied. user=user1 is not the owner of inode=/c/d", which may confuse user. Would
be better to reverse the path back to original mount path.
