Hi,


 Hive calls are blocking calls because once the query is executed it will 
return the ResultSet  from that result set u will get the results.



 "hive.exec.parallel" property will helps to speed up the query execution if 
the query generates more than one independent tasks. If it generates 
independent tasks if this

property is true it will execute the independent tasks parallely otherwise it 
will execute sequentially.



Thanks&Regards,

Chinna Rao Lalam

Hi,

Hive queries take longer time to execute, and by default it is a blocking call. 
Is there any way provided by Hive client to supports non blocking execution.

Also, to execute jobs parallely, I tried setting the "hive.exec.parallel" to 
true in hive-site.xml. But this did not work, Looking at the code, it looks 
like the same flow is been followed both for serial and parallel execution.

Any inputs would be of great help.

Thanks,
Ghousia.
