Rohith commented on YARN-933:
-----------------------------
Sure, I will recheck the code for existence of problem and update the patch.
> 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

> Project: Hadoop YARN

> Components: resourcemanager
> Affects Versions: 2.0.5-alpha
> Reporter: J.Andreina

>
> am max retries configured as 3 at client and RM side.
> Step 1: Install cluster 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.
