Subject [jira] Commented: (HADOOP-2190) dfs ls and lsr commands differ from POSIX standards
Date Fri, 16 Nov 2007 01:46:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2190?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12542930
] 

Mukund Madhugiri commented on HADOOP-2190:
------------------------------------------

Can the command output be along the lines of what we see on linux?

RHEL throws this:
ls: /doesnotexist: No such file or directory

> dfs ls and lsr commands differ from POSIX standards

> Assuming the dfs commands follow POSIX standards, there are some problems with the DFS
ls  and lsr commands. I compared the DFS output with that of RHEL 4u5
> 1. ls a directory when there are no files/directories in that directory:
> Linux: No output
> DFS: Found 0 items
> 2. ls a file/directory that does not exist:
> Linux: ls: /doesnotexist: No such file or directory
> DFS: Found 0 items
> 3. lsr a directory that does not exist:
> Linux: ls: /doesnotexist: No such file or directory
> DFS: No output
