HI all,HIVE runs too slowly when it is doing such things(see the log below),
what's the problem? because I'm joining two large table?it runs pretty fast at
first. when the job finishes 95%, it begins to slow
down.--INFO
Hi list,
I am also facing the same problem. My reducers hang at this position and it
takes hours to complete a single reduce task. Can any hive guru help us out
with this issue.
Thanks,

Hi Edward,
Thanks for replying. I have been using the query
select a,b from a,b where a.id=b.id . According to my knowledge of
Hive, it reads data of both A and B and emits join_key,rowid/required row
data pairs as
You mean select a,b from a inner join b on (a.id=b.id) ? or Does those
brackets make some difference? Because the inner keyword is no where
mentioned in the language manual

Any hints?
