Subject [jira] [Commented] (HADOOP-8616) ViewFS configuration requires a trailing slash
Date Fri, 07 Sep 2012 16:52:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13450780#comment-13450780

Daryn Sharp commented on HADOOP-8616:

Based on my understanding, I'd saying {{ChRootedFileSystem}} is the best place for the fix.
 Anywhere else would be working around its bug.  The handling of the chroot path has always
been a bit complex so maybe this is a good time to simplify it.

>                 URL: https://issues.apache.org/jira/browse/HADOOP-8616
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: viewfs
>    Affects Versions: 0.23.0, 2.0.0-alpha
>            Reporter: Eli Collins
>            Assignee: Sandy Ryza
> 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}
