YifanZhang created IMPALA-12834:
-----------------------------------

             Summary: Add query load information to the query profile
                 Key: IMPALA-12834
                 URL: https://issues.apache.org/jira/browse/IMPALA-12834
             Project: IMPALA
          Issue Type: Improvement
          Components: Perf Investigation
            Reporter: YifanZhang


Add query load information to the query profile to track if the performance regression is related to the insufficient resources of the node, and also recommend if the current pool configurations or host configurations are optimal.

The load information should include:
 * Number of running queries of the executor group on which the query is scheduled
 * Number of running fragment instances of the hosts on which the query is scheduled
 * Used/Reserved memory of the hosts on which the query is scheduled
 * Some other useful metrics
