Last week we resolved a couple JIRAs with a lot of failures in them so we
reduced by more than 50.
>From build #479 to #481 there was an increase in failed unit tests but I think
>it's because of flaky unit tests that we should eventually fix too.
We have been mostly focusing on HDFS so far and now we should try to target
commons, YARN and MapReduce more.
For YARN there are a lot of tests that we are Linux specific and we are
thinking to disable in YARN-8359.
> 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
> Labels: Windows
>
> 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)
