Jeff Zhang commented on TEZ-1233:
---------------------------------
Upload new patch to address the review comments except 1 things
bq. Do we expect any properties which may make sense only at the Vertex level,
but not at the DAG level ?
I don't see any case of this. If this is necessary in future, I think it is
more likely custom vertex property, not standard property in TezConfiguration.
bq. Construction of PropertyScope - is this reflection based approach expensive
?
I think the only way to access annotation is through reflection. Are you
suggesting the way that TezRuntimeConfiguration used ( not use annotation ) ?
> Allow configuration of framework parameters per vertex

> Currently, configuration properties specific in AMConfiguration are used to
> configure tasks - e.g. memory configs, process tree, etc. These should be
> configurable at a Vertex level.
> Also, tasks end up reading these configs from the dist cache each time -
> would be simpler to send over the wire as part of the TaskSpec.
