             Summary: Incorrect executing hosts for custom executor groups in 
query profile 
                 Key: IMPALA-15477
                 URL: https://issues.apache.org/jira/browse/IMPALA-15477
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
            Reporter: Yida Wu
            Assignee: Yida Wu


In clusters configured with multiple custom executor groups under the same set, 
the query profile can report the wrong backend hosts under the Per Host Min 
Memory Reservation and Per Host Number of Fragment Instances info strings.

For example, in a cluster with two custom groups (test-def and test-def1), a 
query correctly routes to and executes on the test-def group, but showing the 
test-def1 nodes in the Per Host Min Memory Reservation and Per Host Number of 
Fragment Instances sections.
