[jira] [Commented] (MAPREDUCE-6834) MR application fails with "No
NMToken sent" exception after MRAppMaster recovery
[ https://issues.apache.org/jira/browse/MAPREDUCE-6834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15876826#comment-15876826 ]
Haibo Chen commented on MAPREDUCE-6834:
---------------------------------------
We have also seen issue very much similar to this. The MR AM was preempted, right after the second attempt was started, it got some container allocations from RM and then MR AM assigned them to tasks attempts. Eventually, the job failed due to too many "No NMToken sent" exceptions in launching containers.

> *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 and application finish correctly
> *Actually:* After launching new MRAppMaster and MRAppAttempt the application fails with the following exception:

> *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 tried to do the same scenario without the commit and application completed successfully after RMAppMaster recovery
