Bikas Saha commented on TEZ-744:
--------------------------------
This is mainly for ease of use. When the vertexmanager takes configuration via
hadoop configuration then the user can put the configuration into the local
tez-site.xml which will go the to DAG. What we could do is use the DAG's conf
(specific to the DAG) instead of AMConf which is created once for the AM.
> Avoid using AM Configuration to initialize VertexManagers

> VertexManagers fallback to using the AMConfiguration for initialization, if
> nothing is specified. We should avoid this if possible.
