Varun Vasudev commented on YARN-2049: ------------------------------------- Couple of things - 1. In the function managementOperation, should there be a null check for token? 2. In the function managementOperation, you call secretManager.cancelToken(dt, UserGroupInformation.getCurrentUser().getUserName()) - should you use getCurrentuser().getUserName? or ownerUGI.getUserName()? The reason I ask is that when creating the token, you're using ownerUGI. > Delegation token stuff for the timeline sever > --------------------------------------------- > > Key: YARN-2049 > URL: https://issues.apache.org/jira/browse/YARN-2049 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Attachments: YARN-2049.1.patch, YARN-2049.2.patch, YARN-2049.3.patch, > YARN-2049.4.patch, YARN-2049.5.patch > > -- This message was sent by Atlassian JIRA (v6.2#6252)
