Íñigo Goiri commented on HADOOP-15475:
--------------------------------------
The number of unit tests failed in the last 6 builds are >5k.
The error seems to be with the native code.
One example
[here|https://builds.apache.org/job/hadoop-trunk-win/475/testReport/].
{code}
java.lang.UnsatisfiedLinkError:

This is an issue that has been coming and going but seems like it's been there
for a while.
Not sure the real reason.
> Fix broken unit tests on Windows

> Key: HADOOP-15475
> URL: https://issues.apache.org/jira/browse/HADOOP-15475
> Project: Hadoop Common
> Issue Type: Test
> Reporter: Anbang Hu
> Assignee: Anbang Hu
> Priority: Minor
>
> There are hundreds of unit tests that fail on Windows. This JIRA tracks the
> effort to fix them.
> The main reasons for unit test failures on Windows are:
> * Windows/Linux path formats (e.g., HDFS-10256).
> * Line separator.
> * Locked files: Windows locks files when opening them.
> ** The typical trigger is not cleaning MiniDFSCluster leaves files locked
> when a test times out; they need to be cleaned using After.
> * Memory lock size.
> * Slow DNS resolution (e.g., HDFS-13569).
> * Locked ports (e.g., HDFS-11700)
