Subject [jira] [Created] (HDFS-7469) Inline permission checking done by FSPermissionChecker#checkSubAccess
Date Wed, 03 Dec 2014 02:07:12 GMT
Haohui Mai created HDFS-7469:
--------------------------------

             Summary: Inline permission checking done by FSPermissionChecker#checkSubAccess
                 Key: HDFS-7469
                 URL: https://issues.apache.org/jira/browse/HDFS-7469
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Haohui Mai
            Assignee: Haohui Mai
         Attachments: HDFS-7469.000.patch

{{FSPermissionChecker#checkSubAccess}} is used by {{getContentSummary()}} and {{computeSnapshotDiff()}}
to validate the permission of the entire subtree through BFS.

As these two calls traverse subtrees to compute the result, the permission checking should
be done during the same traversal.
