--------------------------------
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.
