Subject How to execute parallel jobs inside a query
Date Wed, 22 May 2013 21:30:36 GMT

Hello, everyone

I configured the "hive.exec.parallel" variable to be "true" in the
hive-site.xml and hive-default.xml.
However, each job inside a query still runs sequentially one by one
(though they are supposed to be able to execute concurrently by considering the shape of DAG).
And I also find that the number of "Stages" is always equal to the number
of mapreduce "jobs" (for a query).

Could anyone offer some help?
