Subject [jira] [Created] (HIVE-5908) Use map-join hint to cache intermediate result
Date Thu, 28 Nov 2013 09:39:44 GMT
daxingyu created HIVE-5908:

             Summary: Use map-join hint to cache intermediate result
                 Key: HIVE-5908
             Project: Hive
          Issue Type: New Feature
          Components: Query Processor
            Reporter: daxingyu
            Priority: Minor
             Fix For: 0.13.0

There are very complicated query exists in our project , especially some intermediate result
can be very small . But hive will treat these result as a part  of mapreduce job , which is
very costly.

So i am proposed to use map-join hint to cache these small result, and speed up the hive job
