             Summary: AdmissionControlTimeSinceLastUpdate TIME_MS counter breaks some profile consumers
                 Key: IMPALA-8235
                 URL: https://issues.apache.org/jira/browse/IMPALA-8235
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 3.2.0
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


The issue is:
* type is a required field for TCounter with enum type TUnit
* Some readers (e.g. Java) that encounter an unknown enum value replace it it with null, then throw an exception because it is a required field

This means that the workflow for adding a new TUnit is basically broken, since we can't add a unit in Impala then update readers later.

I think we should switch to TIME_NS then reconsider the workflow here.
