---------------------------------------

             Summary: Add the value of the http ‘X-Forwarded-For’ header to the 
runtime profile
                 Key: IMPALA-13310
                 URL: https://issues.apache.org/jira/browse/IMPALA-13310
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 4.4.0
            Reporter: Andrew Sherman
            Assignee: Andrew Sherman


When using hs2-http protocol, http messages from Impala clients may pass 
through one or more proxies before reaching the Impala coordinator. This can 
make it harder to track the origin of the http messages. The X-Forwarded-For 
header is added or edited by HTTP proxies when forwarding a request. Add the 
value of this header to the runtime profile so that it can be observed. Note 
that Impala does not do any verification of this value, so its value should 
only be trusted if the deployment system protects against spoofing.
