TestAclCommands was coded on the HDFS-4685 branch to stub just enough behavior to satisfy the ls command's usage of the Globber. HADOOP-10338 recently changed the Globber, and now the stubbing isn't quite sufficient, so the tests fail.
Cannot get the FileStatus of the root inode from the new Globber
Hadoop Common changes required to support HDFS ACLs.
This patch is a small change in the stubbing done by TestAclCommands to get the test passing again.
Thanks for the quick review, Haohui. I committed it to the feature branch.
