             Summary: RBF throw IndexOutOfBoundsException with disableNameServices
                 Key: HDFS-16728
                 URL: https://issues.apache.org/jira/browse/HDFS-16728
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: ZanderXu
            Assignee: ZanderXu


RBF will throw an IndexOutOfBoundsException when the namespace is disabled.

Suppose we have a mount point /a/b -> ns0 -> /a/b and we disabled the ns0.  

RBF will throw IndexOutOfBoundsException during handling requests with path starting with /a/b.
