-----------------------------------
Summary: Move per-host resource utilization counters to per-host
profiles in coordinator
Key: IMPALA-8126
URL: https://issues.apache.org/jira/browse/IMPALA-8126
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 3.2.0
Reporter: Lars Volker
Once IMPALA-7694 gets in we should move the per-host resource utilization
counters in {{Coordinator::ComputeQuerySummary()}} to the host profiles in
{{Coordinator::BackendState}}.

We could also simplify BackendState::ComputeResourceUtilization() to just use
the per-backend counters instead of iterating over fragments.
I think there may be some compatibility concerns about removing these -
existence of the counters isn't contractual but we don't want to break useful
tools if avoidable.
For example, I confirmed that Cloudera Manager actually does parse the existing
strings (which is a little sad, but understandable given the lack of other
counters).
