Roger Whitcomb commented on VFS-523:
------------------------------------
Hi Bernd,
The code I'm using is in the Apache Pivot project in the VFSFileBrowser and
related classes. The failure I noticed, specifically, was that two
HdfsFileObjects had the same path on different file systems, and they had the
"equals" method return true. I believe the code is consistently calling
"equals" for these types of comparisons, but I don't know if all the tests are
!equals or just equals. I would think that defaulting to the generic
Object.equals would probably be fine.
So, I will test your latest patch as soon as I return to the office on Tuesday
(unfortunately I am not in a position to try it until then).
Thank you for the investigation on this.

> Key: VFS-523
> URL: https://issues.apache.org/jira/browse/VFS-523
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: 2.1
> Environment: Windows 7
> Reporter: Roger Whitcomb
> Priority: Minor
> Labels: hdfs
> Fix For: 2.1
>
> Attachments: hdfsequal.diff, unify-hdfs-equals.patch

> If I construct two HdfsFileObject referring to the same path (for instance,
> "/") but on different hosts, the "equals" method will consider them equal
> (and the "hashCode" method will give the same results for both) even though
> they clearly refer to different files since they are on different hosts.
> These two methods should also factor in the HdfsFileSystem to the equation.
