-------------------------------------
Summary: Profile counter that indicates if a process or JVM pause
occurred
Key: IMPALA-9046
URL: https://issues.apache.org/jira/browse/IMPALA-9046
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 3.3.0
Reporter: Tim Armstrong
Assignee: Tim Armstrong
We currently log a message if a process or JVM pause is detected but there's no
indication in process. I suggest that we should:
* Add metrics that indicate the number and duration of detected pauses
* Add counters to the backend profile for the deltas in those metrics
