>             Project: Apache Tez
>          Issue Type: Improvement
>            Reporter: László Bodor
>            Assignee: Hankó Gergely
>            Priority: Major
>             Fix For: 0.10.3

> Codebase is full of long call chains like:
> {code}
> taskAttemptID.getTaskID().getVertexID().getDAGId()
> {code}
> I think, with more convenient API methods we can avoid these calls in the codebase.
> A taskattempt->task->vertex->dag relation is somewhat constant, so e.g. we should have access to the dag through taskattempt.getDAGId().
