 {code:java}   
ContainerId t1a2contId = task1Attempt2.getAssignedContainerID();
LOG.info(t1a2contId.toString());
{code}

TaskAttempt2 may not have been assigned a container, this is why there is a 
NPE. Uploading a trivial patch to fix this.

> This issue was found from a cluster where Pig query occasionally failed on

[jira] [Commented] (MAPREDUCE-6754) Container Ids for an yarn application should be monotonically increasing in the scope of the application

Srikanth Sampath commented on MAPREDUCE-6754:

Thanks much [[~jlowe][[~vinodkv][[~jianhe]  Given the discussion above, we can 
just add the attemptId to the JvmId for now.  I will consider nuking out JvmId 
separately.

> Key: MAPREDUCE-6754

> Currently across application attempts, container Ids are reused.  The 
> container id is stored in AppSchedulingInfo and it is reinitialized with 
> every application attempt.  So the containerId scope is limited to the 
> application attempt.
> In the MR Framework, It is important to note that the containerId is being 
> used as part of the JvmId.  JvmId has 3 components  containerId>.  The JvmId is used in datastructures in TaskAttemptListener and 
> is passed between the AppMaster and the individual tasks.  For an application 
> attempt, no two tasks have the same JvmId.
> This works well currently, since inflight tasks get killed if the AppMaster 
> goes down.  However, if we want to enable WorkPreserving nature for the AM, 
> containers (and hence containerIds) live across application attempts.  If we 
> recycle containerIds across attempts, then two independent tasks (one 
> inflight from a previous attempt  and another new in a succeeding attempt) 
> can have the same JvmId and cause havoc.
> This can be solved in two ways:
> *Approach A*: Include attempt id as part of the JvmId. This is a viable 
> solution, however, there is a change in the format of the JVMid. Changing 
> something that has existed so long for an optional feature is not persuasive.
> *Approach B*: Keep the container id to be a monotonically increasing id for 
> the life of an application. So, container ids are not reused across 
> application attempts containers should be able to outlive an application 
> attempt. This is the preferred approach as it is clean, logical and is 
> backwards compatible. Nothing changes for existing applications or the 
> internal workings.  
> *How this is achieved:*
> Currently, we maintain latest containerId only for application attempts and 
> reinitialize for new attempts.  With this approach, we retrieve the latest 
> containerId from the just-failed attempt and initialize the new attempt with 
> the latest containerId (instead of 0).   I can provide the patch if it helps. 
>  It currently exists in MAPREDUCE-6726
