On the testcases, I've modified the tests cases to assert an instance different from the singleton is used when set. I was expecting a more involved test case wherein it is using nmclient and amrmclient to get the container and do start/getContainer call. This will ideally test sharing nmtokens between nmclient and amrmclient in multi am case. thoughts? > NMTokenCache is a a singleton, prevents multiple AMs running in a single JVM to work correctly > ---------------------------------------------------------------------------------------------- > > Key: YARN-1321 > URL: https://issues.apache.org/jira/browse/YARN-1321 > Project: Hadoop YARN > Issue Type: Bug > Components: client > Affects Versions: 2.2.0 > Reporter: Alejandro Abdelnur > Assignee: Alejandro Abdelnur > Priority: Blocker > Fix For: 2.2.1 > > Attachments: YARN-1321.patch, YARN-1321.patch, YARN-1321.patch, YARN-1321.patch > > > NMTokenCache is a singleton.
