Giovanni Matteo Fumarola commented on YARN-8164:
Thanks [~xiaoheipangzi] for the patch and for the tool. I am going to try it
out.
LGTM +1.
CapacityScheduler, FifoScheduler and FairScheduler can return null for
getAppsInQueue.
[~elgoiri]. Can please you push it on trunk and branch-2?
> Fix a Potential NPE

> Key: YARN-8164
> URL: https://issues.apache.org/jira/browse/YARN-8164
> Project: Hadoop YARN
> Issue Type: Bug
>Affects Versions: 3.0.0-beta1
>Reporter: lujie
>Assignee: lujie
>Priority: Major
> Attachments: YARN-8146_1.patch, YARN-8146_2.patch
>
>
> We have developed a static analysis tool
> [NPEDetector|https://github.com/lujiefsi/NPEDetector] to find some potential
> NPE. Our analysis shows that some callees may return null in corner case(e.g.
> node crash , IO exception), some of their callers have _!=null_ check but
> some do not have.
> Callee FairScheduler#getAppsInQueue can return null
> {code:java}
> public List getAppsInQueue(String queueName) {
> FSQueue queue = queueMgr.getQueue(queueName);
>if (queue == null) {
> return null;//here
> }
> }
> {code}
> it has 4 callers, three of them have null checker, one does not have. In this
> issue we post a patch which can add !=null based on existed !=null check.
