J.Andreina created YARN-933:
-------------------------------

             Summary: After an AppAttempt_1 got failed [ removal and releasing of container
is done , AppAttempt_2 is scheduled ] again relaunching of AppAttempt_1 throws Exception at
RM .And client exited before appattempt retries got over
                 Key: YARN-933
                 URL: https://issues.apache.org/jira/browse/YARN-933
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 2.0.5-alpha
            Reporter: J.Andreina


Hostname enabled.
am max retries configured as 3 at client and RM side.

Step 1: Install cluster in HA mode with NM on 2 Machines 
Step 2: Make Ping using ip from RM machine to NM1 machine as successful ,But using Hostname
should fail
Step 3: Execute a job
Step 4: After AM [ AppAttempt_1 ] allocation to NM1 machine is done , connection loss happened.

Observation :
==========
After AppAttempt_1 has moved to failed state ,release of container for AppAttempt_1 and Application
removal are successful. New AppAttempt_2 is sponed.

1. Then again retry for AppAttempt_1 happens.
2. Again RM side it is trying to launch AppAttempt_1, hence fails with InvalidStateTransitonException
3. Client got exited after AppAttempt_1 is been finished [But actually job is still running
], while the appattempts configured is 3 and rest appattempts are all sponed and running.
