Luca Telloli commented on HDFS-456:
-----------------------------------
To answer my own question, I run the test on trunk + HDFS-496 30 times
consecutively, for 2 times.
The first time it passed 12 times, and failed 18; the second time it failed 23
times and passed 7 times.
In the second batch I saved the test logs and they all fail for the same error
below, which is the same error that makes the test fail with HDFS-396 reverted,
so that I'd conclude that this patch does not impact that test. The error seems
related to something left open, and I assume it's OS specific.

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: name-node
> Affects Versions: 0.21.0
> Reporter: Konstantin Shvachko
> Assignee: Luca Telloli
> Fix For: 0.21.0

> There are several problems with recent commit of HDFS-396.
> # It does not work with default configuration "file:///". Throws
> {{IllegalArgumentException}}.
> # *ALL* hdfs tests fail on Windows because "C:\mypath" is treated as an
> illegal URI. Backward compatibility is not provided.
> # {{IllegalArgumentException}} should not be thrown within hdfs code because
> it is a {{RuntimException}}. We should throw {{IOException}} instead. This
> was recently discussed in another jira.
> # Why do we commit patches without running unit tests and test-patch? This is
> the minimum requirement for a patch to qualify as committable, right?
