Tsuyoshi OZAWA commented on YARN-1911:
--------------------------------------

Thank you for taking this JIRA, [~kj-ki]. IMO, we should add test code to prevent this kind
of bugs. How about adding tests under hadoop-yarn-project/hadoop-yarn/hadoop-yarn-api/src/test/java/org/apache/hadoop/yarn/api/records/TestResourceOption.java?
[~djp], what do you think?

> I'm trying to implement REST API for Dynamic configuration. But NullPointerException
occurred when ResourceOption.getOverCommitTimeout() called. Here is a sample code with error
