László Bodor updated HIVE-27639:
--------------------------------
Summary: Query level performance counters (was: Performance counters for
easier investigations)
> Query level performance counters
> --------------------------------
>
> Key: HIVE-27639
> URL: https://issues.apache.org/jira/browse/HIVE-27639
> Project: Hive
> Issue Type: Improvement
> Reporter: László Bodor
> Priority: Major
>
> We need to move performance measurements to the next level and implement
> whatever is needed to make us able to find easier answers to problems like
> “query is slow”. The problem is that we keep digging into logs + watching
> metrics that are provided by *something* in the environment (that can be
> anything that the actual vendor implements outside of hive).
> Let's try to localize the environment problems to the interval of the slow
> query and make it exposed through counters.
> Also, let's keep in mind that performance measurements ideally should never
> cause performance problems itself: heavyweight measurements should be
> disabled by default.
