Environment: Centos 7
Reporter: Aleksandr Balitsky
Priority: Critical
*Steps to reproduce:*
1) Submit MR application (for example PI app with 50 containers)
2) Find MRAppMaster process id for the application
3) Kill MRAppMaster by kill -9 command
*Expected:* ResourceManager launch new MRAppMaster container and MRAppAttempt

*Problem*:
When RMCommunicator sends "registerApplicationMaster" request to RM, RM
generates NMTokens for new RMAppAttempt. Those new NMTokens are transmitted to
RMCommunicator in RegisterApplicationMasterResponse
(getNMTokensFromPreviousAttempts method). But we don't handle these tokens in
RMCommunicator.register method. RM don't transmit tese tokens again for other
allocated requests, but we don't have these tokens in NMTokenCache. Accordingly
we get "No NMToken sent for node" exception.
I have found that this issue appears after changes from the
https://github.com/apache/hadoop/commit/9b272ccae78918e7d756d84920a9322187d61eed
I tried to do the same scenario without the commit and application completed
successfully after RMAppMaster recovery
