             Summary: RM with lost NMs results in massive log of AppAttemptId doesnt exist in cache
                 Key: MAPREDUCE-4672
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4672
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 0.23.1
            Reporter: Chris Riccomini


Hey Guys,

I'm running a 9 node cluster with 8 NMs and a single RM node. If I run an app master and have that app master start a container, then shut down all nodes (to simulate a complete failure), the containers timeout and fail, as expected.

What's unexpected is that my log then starts filling with:


2012-09-21 18:02:02,614 ERROR resourcemanager.ApplicationMasterService (ApplicationMasterService.java:allocate(247)) - AppAttemptId doesnt exist in cache appattempt_1348248013002_0001_000001

2012-09-21 18:02:07,623 ERROR resourcemanager.ApplicationMasterService (ApplicationMasterService.java:allocate(247)) - AppAttemptId doesnt exist in cache appattempt_1348248013002_0001_000001

Is there any way to shut this off/fix it? It just keeps going forever, until I bounce the RM node.

Thanks!
Chris
