-------------------------------------
Summary: Shell PathData parsing failures on Windows
Key: HADOOP-8953

Daryn Sharp commented on HADOOP-8953:
-------------------------------------
What we really should be doing is removing the drive letter support from {{Path}}. Uris formatted according to the MSDN article shouldn't require the special handling.

Ivan Mitic commented on HADOOP-8953:
------------------------------------
Thanks Arpit for the patch.
bq. In one of the original windows jiras it was agreed that going forward only standard uris will be supported by hadoop.
Right, we agreed on only supporting valid URIs in HADOOP-8409 for hadoop generic options. The same should hold on trunk.
Arpit, please wait for me to review and test the patch. The goal of the patch is to fix the above two unittests, right? Two early comments
- I don't think we want to have Windows specific code in FileSystem.java
- PathData seems to replicate a lot of the logic from Path, can we avoid this?

Daryn Sharp commented on HADOOP-8953:
-------------------------------------
I replied to our offline discussion. I'm really uneasy with all the PathData changes when they are working around a problem caused by the artificial ban on ":" in Paths that is preventing well-formed URIs with drive letters from working.

Chris Nauroth commented on HADOOP-8953:
---------------------------------------
Some ideas have been discussed for refactoring Path and its numerous call sites. That's a fairly large scope considering how many other classes are coupled to Path, and the fact that many callers assume return values of a certain format to use in additional string concatenation.
At this point, we'd prefer to work towards full test pass on Windows with minimal changes to the current trunk code, and then refactor slowly towards the ideal state after we have those tests as a safety net. This would be a conservative approach towards improving the codebase's path handling logic.

Release Note: Support Windows paths with drive specifiers. This is currently broken on branch-trunk-win.
Status: Patch Available (was: Open)
Resolves TestPathData failures. The patch may need to be updated as we resolve more path-related issues on Windows.

This would be a conservative approach towards improving the codebase's path handling logic.
I generally agree that minimal change is best. I may not understand the whole problem here, but it appears the cart is dragging the horse? Ie. Are moving in the wrong direction with {{FileSystem}} to appease a test? Unfortunately the original patch was deleted (please don't do that, just post another) so I can't refer back the problem in its entirety.
Note that the change to the {{PathData}} test is breaking what it's trying to test: path in = path out. I spent a lot of effort trying to ensure that the output path matches the input to allow scripts to easily parse the output when multiple args are given.

What format are the URIs? I would expect file uris formatted per this link to work, if not, it's a bug:
http://blogs.msdn.com/b/ie/archive/2006/12/06/file-uris-in-windows.aspx
In one of the original windows jiras it was agreed that going forward only standard uris will be supported by hadoop.

Hi Daryn, would you have a link to the jira handy? File URIs formatted as described in that MSDN article should work already.

---------------------------------------
Arpit, could you upload a new version of the patch? It looks like the current version was generated without the git diff --no-prefix option. Also, I got this compilation error:
[ERROR] /Users/chris/git/hadoop-common/hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/fs/shell/TestPathData.java:[123,12] WINDOWS is not public in org.apache.hadoop.fs.Path; cannot be accessed from outside package
I'm guessing that the idea was to make Path.WINDOWS public, or to use the equivalent Shell.WINDOWS, which is already public.
Thanks!

Sanjay, I completely agree. I just feel the change is more complicated than necessary, so I'm working offline with Arpit and Chris to see if there's a simpler solution.

Daryn Sharp commented on HADOOP-8953:
-------------------------------------
bq. PathData seems to replicate a lot of the logic from Path, can we avoid this?
Sadly, no. The {{Path}} object will munge the path in various ways such that you can't get the string back used to create the {{Path}} object. This requires {{PathData}} to maintain its own copy of the path string so the output to the user matches exactly what they provided to the command. {{Path}} also strips trailing slashes which breaks the shell's ability to disambiguate if the path is to be treated as a directory.

Arpit Agarwal commented on HADOOP-8953:
---------------------------------------
Daryn, the goal is to support Windows paths that do not conform to the URI syntax and not just appease the test.
However the patch can be updated to maintain the PathData invariant (path in = path out). I am also looking into avoiding the change to FileSystem.

Given that this change is needed for making progress on gettign 100% unit tests passing on Windows, I recommend creating a follow on jira for completing the discussion and finishing the remaining discussion. Arpit, can you create another jira?

bq. In one of the original windows jiras it was agreed that going forward only standard uris will be supported by hadoop.
The agreement was that HDFS paths will not allow windows back slashes. We still have to support the local OS's path format. This patch is only fixing for local paths for windows (ie paths that begin with "x:").

---------------------------------------
Daryn suggested a few further improvements to make Windows URI handling more rigorous and I have filed HADOOP-9018 to track them.
I would like to avoid inflating the scope of HADOOP-8953 and allow us to make forward progress with getting Windows support working in trunk-win.
