Subject [jira] [Commented] (HADOOP-9912) globStatus of a symlink to a directory does not report symlink as a directory
Date Tue, 03 Sep 2013 16:02:52 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13756725#comment-13756725
] 

Daryn Sharp commented on HADOOP-9912:
-------------------------------------

This {{Globber}} re-write is problematic, and the optimization we are talking about is very
broken regardless of whether we call file or link status.  Both of these calls in {{Globber}}
are trapping {{IOException}} and returning null.  This unexpectedly causes file not found
exceptions.

Let's say I have "/dir/noperms/file".  If I do a ls on /dir/noperms, I get a permission denied.
 If I do ls on /dir/noperms/file I get no such file or directory.

If I do a ls on a standby, the {{StandbyException}} is trapped, and I get no such file or
directory.
