> 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: Tamas Mate
> Priority: Major
>
> We currently log a message if a process or JVM pause is detected but there's no indication in the query profile if it got affected. 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
