Jimmy Xiang commented on HIVE-13026:
------------------------------------
[~szehon]/[~aihuaxu], I tested this in my local HS2 and found these metrics
don't decrease even after my client is closed for a while.
> Pending/running operation metrics are wrong

> A query is finished, however the pending/running operation count doesn't
> decrease.
> For example, in TestHs2Metrics::testMetrics(), we have
> {noformat}
> MetricsTestUtils.verifyMetricsJson(json, MetricsTestUtils.TIMER,
> "api_hs2_operation_PENDING", 1);
> MetricsTestUtils.verifyMetricsJson(json, MetricsTestUtils.TIMER,
> "api_hs2_operation_RUNNING", 1);
> MetricsTestUtils.verifyMetricsJson(json, MetricsTestUtils.COUNTER,
> "hs2_completed_operation_FINISHED", 1);
> {noformat}
> Should it be below?
> {noformat}
> MetricsTestUtils.verifyMetricsJson(json, MetricsTestUtils.TIMER,
> "api_hs2_operation_PENDING", 0);
> MetricsTestUtils.verifyMetricsJson(json, MetricsTestUtils.TIMER,
> "api_hs2_operation_RUNNING", 0);
> MetricsTestUtils.verifyMetricsJson(json, MetricsTestUtils.COUNTER,
> "hs2_completed_operation_FINISHED", 1);
> {noformat}
