[jira] [Created] (IMPALA-6091) Impala Queries Executing long time (long running impala queries)

Venkat Atmuri created IMPALA-6091:
-------------------------------------

             Summary: Impala Queries Executing long time (long running impala queries)
                 Key: IMPALA-6091
                 URL: https://issues.apache.org/jira/browse/IMPALA-6091
             Project: IMPALA
          Issue Type: Bug
         Environment: Impala Shell v2.7.0-cdh5.10.1
            Reporter: Venkat Atmuri
         Attachments: impala executing time.PNG

I'm seeing a lot of simple queries like, “SELECT * FROM DATABASE.TABLE”, “SHOW TABLES” and “DESCRIBE database.table” that hang around in the list and say they’re Executing, even 90-170 minutes after they’ve completed. 

I would like to know if there is a way to configure Impala to stop/cancel a long-running query after a certain amount of time.

Found the below link to set time limit but were using TABLEAU so need more time for tableau(6 users) queries.

It seems like it’s almost necessary to run two instances of Impala (one for Tableau and one for all other requests).
 
Any suggestions?
 
 
 
Thanks.
