Subject [jira] [Commented] (HDFS-4434) Provide a mapping from INodeId to INode
Date Sat, 06 Apr 2013 00:39:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4434?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13624236#comment-13624236
] 

Sanjay Radia commented on HDFS-4434:
------------------------------------

The check for reserved names occurs after permission checks are done. Is this the behavior
we want?
Note we check for valid names early in each of the fs operation. Reserved names are kind of
like invalid names operations such a create-file, mkdir, rename, create-symlink, etc.
