Jonathan Eagles resolved TEZ-325.
    Resolution: Won't Fix

This is a good idea, but I think it has stagnated. Closing this old jira.

> Allow work units to be assigned to running tasks

>                 Key: TEZ-325
>                 URL: https://issues.apache.org/jira/browse/TEZ-325
>             Project: Apache Tez
>          Issue Type: New Feature
>            Reporter: Siddharth Seth
>            Priority: Major
> An extension of container reuse. Instead of re-initializing new data structures for each
task run by a container - this is to allow a work unit to be given to the task so that it
can make use of existing structures.
> As an example - reusing sort buffers when running map tasks, Hive may need to generate
some vertex level information - which is the same across all tasks in a vertex.
