             Summary: Automatically capture test cases for queries.
                 Key: IMPALA-8773
                 URL: https://issues.apache.org/jira/browse/IMPALA-8773
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: bharath v

It will be helpful to have a session option, something like 
ENABLE_AUTO_TESTCASE_COLLECTION, which the users can set in a session and the 
test cases for all the QueryStmts running in that session are captured in a 
directory. This way, users don't need run "create testcase" for each query 
individually. Should be turned off by default.

Since this potentially increases the planning time, a warning in the runtime 
profile would be helpful for debugging.
