-------------------------------------
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.
