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.
> globStatus of a symlink to a directory does not report symlink as a directory
