Sigma-Ma opened a new pull request, #8689: URL: https://github.com/apache/hbase/pull/8689
**What changes were proposed in this pull request?** Backport #8563 to branch-2, adding the overall `oldestProcedureAge` gauge and per-procedure-type gauges. The implementation uses `getProcedures()` and excludes finished procedures. The backport places the metrics implementation in `hbase-hadoop2-compat` and uses Java 8-compatible collection APIs in the test. **Why are the changes needed?** These metrics help identify long-running master procedures on branch-2. Per-type gauges allow operators to monitor different procedure types independently. **How was this patch tested?** Passed on JDK 8: `mvn -pl hbase-server -am -Dtest=TestOldestProcedureMetrics,TestMetricsMasterProcSourceImpl,TestMasterMetrics -Dsurefire.failIfNoSpecifiedTests=false clean test` Passed on JDK 17: `mvn -pl hbase-hadoop-compat,hbase-hadoop2-compat,hbase-server spotless:check`. -- This is an automated message from the Apache Git Service.
