Hitesh Shah commented on TEZ-1153:
----------------------------------
[~rohini] Using the dag lifecycle, this can already be done. However, there is
no support for memory management currently hence if you do plan to cache
objects across multiple vertices, please use this with care.
For a container, there is no real control mechanism to inform it which vertices
are done/not done/re-scheduled hence cache clean up is only supported when a
container runs a task of a different vertex or a different dag.
> Allow object caching for more than one vertex

> by specifying a list of vertex ids
