--------------------------------
Summary: NPE if AM attempts to register before RM processes launch
event
Key: YARN-3260
URL: https://issues.apache.org/jira/browse/YARN-3260
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.6.0
Reporter: Jason Lowe
The RM on one of our clusters was running behind on processing AsyncDispatcher
events, and this caused AMs to fail to register due to an NPE. The AM was
launched and attempting to register before the RMAppAttemptImpl had processed
the LAUNCHED event, and the client to AM token had not been generated yet. The
NPE occurred because the ApplicationMasterService tried to encode the missing
token.
