[jira] [Commented] (HADOOP-7209) Extensions to FsShell
[ https://issues.apache.org/jira/browse/HADOOP-7209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13238530#comment-13238530 ]
Daryn Sharp commented on HADOOP-7209:
-------------------------------------
I believe that all the features, except {{rmdir --ignore-fail-on-non-empty}}, are implemented. I'm having difficulty understanding the use case for the ignore flag. When would the user want to remove a directory but not care if it wasn't removed?

> ---------------------

> Key: HADOOP-7209
> URL: https://issues.apache.org/jira/browse/HADOOP-7209
> Project: Hadoop Common
> Issue Type: Improvement
> Affects Versions: 0.20.3
> Reporter: Olga Natkovich
> Assignee: Daryn Sharp
> Fix For: 0.24.0
>
>
> Our project, Pig, exposes FsShell functionality to our end users through a shell command. We want to use this command with no modifications to make sure that whether you work with HDFS through Hadoop or Pig you get identical semantics.
> The main concern that has been recently raised by our users is that there is no way to ignore certain failures that they consider to be benign, for instance, removing a non-existent directory.
> We have 2 asks related to this issue:
> (1) Meaningful error code returned from FsShell (we use java class) so that we can take different actions on different errors
> (2) Unix like ways to tell the command to ignore certain behavior. Here are the commands that we would like to be expanded/implemented:
> * rm -f
> * rmdir ---ignore-fail-on-non-empty
> * mkdir -p
