Subject [jira] [Commented] (HADOOP-8409) Address Hadoop path related issues on Windows
Date Thu, 31 May 2012 22:29:23 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13287009#comment-13287009

Ivan Mitic commented on HADOOP-8409:

Thanks guys for your comments and valid concerns! Daryn, before you brought up the issue with
the backslash, I was building based on the assumption that it is supported by Hadoop (hence
the disconnect).

In line with this, I spent quite a bit of time thinking about pros and cons to having Path
object support backslash VS not. Both approaches have legitimate pros and cons. Once I sum
them up on my end, I'll reply back.

>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs, test, util
>    Affects Versions: 1.0.0
>            Reporter: Ivan Mitic
>            Assignee: Ivan Mitic
>         Attachments: HADOOP-8409-branch-1-win.patch
>   Original Estimate: 168h
>  Remaining Estimate: 168h
> There are multiple places in prod and test code where Windows paths are not handled properly.
From a high level this could be summarized with:
> 1. Windows paths are not necessarily valid DFS paths (while Unix paths are)
> 2. Windows paths are not necessarily valid URIs (while Unix paths are)
> #1 causes a number of tests to fail because they implicitly assume that local paths are
valid DFS paths (by extracting the DFS test path from for example "test.build.data" property)
> #2 causes issues when URIs are directly created on path strings passed in by the user
