> If the viewfs config doesn't have a trailing slash commands like the following fail:
> {noformat}
> 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> ...]
> {noformat}
> We hit this problem with the following configuration because "hdfs://ha-nn-uri" does
not have a trailing "/".
> {noformat}
>   <property>
>   <name>fs.viewfs.mounttable.foo.link./nameservices/ha-nn-uri</name>
>   <value>hdfs://ha-nn-uri</value>
>   </property>
> {noformat}
