I submit 5 queries from 5 different scripts. When I use hive cli, I could see
all these 5 queries related jobs in application tracker in different states (
running/accepted etc). When I submit through beeline only one job I see in
application tracker. Other job I can see only after first job finishes.
Ex: hive –f script1.hql &
Hive –f script2.hql &
Hive –f script3.hql &
Hive –f script4.hql &
Hive –f script5.hql &

Chaudra,
The difference you saw between Hive CLI and Beeline might indicate a bug.
However, before making such a conclusion, could you give an example of your
queries? Are the jobs you expect to run parallel for a single query? Please
note that your script file is executed line by line in either case.

Hi,
Currently I am submitting multiple hive jobs using hive cli with “hive –f”
from different scripts. All these jobs I could see in application tracker and
these get processed in parallel.
Now I planned to switch to HiveServer2 and submitting jobs using beeline client
from multiple scripts example : “nohup beeline -u
jdbc:hive2://<host>:<port>#<variable>=$epoch -n <user> -p <pass> -d
org.apache.hive.jdbc.HiveDriver -f <hql script>.hql &”.
But I could see jobs get submitted in serial. Only one job appears in
application tracker at a time even though cluster resources are available. Once
that job finishes then only other job get submitted. Why is that? Is there any
setting needs to be set to submit jobs in parallel?
Thanks,
Chandra
