[jira] [Commented] (HADOOP-8409) Address Hadoop path related issues
on Windows
[ 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.

> 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
