Siyao Meng commented on HADOOP-16264:
-------------------------------------

[~giovanni.fumarola] Sure. I just uploaded the result of a new run in  
[^test-run2.log.gz]. After backporting HADOOP-12760 + HADOOP-15775 + 
HADOOP-16016 on top of branch-3.1.2, there are significantly less unit test 
failures already. Only 12 out of 96 maven projects have at least one unit test 
failures now. Here are the results containing the failed/erred unit tests and 
stack traces extracted from the full log:

> [JDK11] Track failing Hadoop unit tests
> ---------------------------------------
>
>                 Key: HADOOP-16264
>                 URL: https://issues.apache.org/jira/browse/HADOOP-16264
>             Project: Hadoop Common
>          Issue Type: Task
>    Affects Versions: 3.1.2
>            Reporter: Siyao Meng
>            Assignee: Siyao Meng
>            Priority: Major
>         Attachments: test-run1.tgz, test-run2.log.gz

> Although there are still a lot of work before we could compile Hadoop with 
> JDK 11 (HADOOP-15338), it is possible to compile Hadoop with JDK 8 and run 
> (e.g. HDFS NN/DN,YARN NM/RM) on JDK 11 at this moment.
> But after compiling branch-3.1.2 with JDK 8, I ran unit tests with JDK 11 and 
> there are a LOT of unit test failures (44 out of 96 maven projects contain at 
> least one unit test failures according to maven reactor summary). This may 
> well indicate some functionalities are actually broken on JDK 11. Some of 
> them already have a jira number. Some of them might have been fixed in 3.2.0. 
> Some of them might share the same root cause.
> By definition, this jira should be part of HADOOP-15338. But the goal of this 
> one is just to keep track of unit test failures and (hopefully) resolve all 
> of them soon.
