Change subject: IMPALA-11553: Add event specific metrics in the table metrics ...................................................................... IMPALA-11553: Add event specific metrics in the table metrics This patch adds an event specific metric "avg-events-process-duration" at the table level metrics. This metric is also extended to last 1min, 5mins, 15mins duration. This mertic is useful to identify the average events processed duration on the table. This is helpful to identify if a particular table is causing event procssor lagging and as a temporary workaround, event processing can be disabled on that table. Another metric is also added in the event processor summary page, "events-consuming-delay-ms", is the time difference in milliseconds of the event created in the metastore and event processed by event processor. This is another useful metric to gauge how the event processor is lagging. Tests: - Manually verified the metrics on catalogD UI page when running some hive workloads.
