--------------------------------------
Very good, I've added that information in the wiki:
* [Configuration Properties -- hive.fetch.task.conversion |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.fetch.task.conversion]
I'll put a note on HIVE-5718 so the wiki can be revised when it's committed.
> Support non-MR fetching for simple queries with select/limit/filter
> operations only

> It's trivial but frequently asked by end-users. Currently, select queries
> with simple conditions or limit should run MR job which takes some time
> especially for big tables, making the people irritated.
> For that kind of simple queries, using fetch task would make them happy.
