Jeff Zhang commented on TEZ-1233:
---------------------------------
bq. Would it be better to rely on prefixes instead? This will also help in
creating better named property configs. If some of the configs need to be
renamed, we can make use of deprecation to ensure existing users do not break.
using prefix works but may introduce more effort to maintain the deprecated
property if them don't follow the prefix rule. We have to hard code to verify
whether it is correctly to set this property in dag/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.
