------------------------------------------------------------
[~stakiar]: can you assign this jira to me ? I guess this feature is need by
HIVE-17486 and once HIVE-17486 is resolved, it is better to show whether the
table is cached or not in explain.

> Project: Hive
> Issue Type: Sub-task
> Components: Spark
> Reporter: Sahil Takiar
> Assignee: liyunzhang
> Priority: Major
>
> It would be nice if the explain plan showed what {{MapWork}} / {{ReduceWork}}
> objects are being cached by Spark.
> The {{CombineEquivalentWorkResolver}} is the only code that triggers Spark
> cache-ing, so we should be able to modify it so that it displays if a work
> object will be cached or not.
