Subject [jira] [Updated] (HADOOP-8616) ViewFS configuration requires a trailing slash
Date Tue, 02 Oct 2012 01:25:08 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8616?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Aaron T. Myers updated HADOOP-8616:

    Attachment: HADOOP-8616.patch

Right after I initially committed the patch, I realized that the new test file was missing
the Apache license header. Here's an updated patch which just adds that missing license.

I've reverted my initial commit, and am going to commit this updated patch now, since it differs
only in the comment.

>                 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
>         Attachments: HADOOP-8616.patch, HADOOP-8616.patch, HADOOP-8616.patch
> 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}
