[jira] [Created] (HADOOP-8616) ViewFS configuration requires a trailing slash

Eli Collins created HADOOP-8616:
-----------------------------------

             Summary: ViewFS configuration requires a trailing slash
                 Key: HADOOP-8616
                 URL: https://issues.apache.org/jira/browse/HADOOP-8616
             Project: Hadoop Common
          Issue Type: Bug
          Components: viewfs
    Affects Versions: 2.0.0-alpha, 0.23.0
            Reporter: Eli Collins


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}
