Description

If the viewfs config doesn't have a trailing slash commands like the following fail:

bash-3.2$ hadoop fs -ls
-ls: Can not create a Path from an empty string
Usage: hadoop fs [generic options] -ls [-d] [-h] [-R] [<path> ...]

We hit this problem with the following configuration because "hdfs://ha-nn-uri" does not have a trailing "/".

  <property>
  <name>fs.viewfs.mounttable.foo.link./nameservices/ha-nn-uri</name>
  <value>hdfs://ha-nn-uri</value>
  </property>
