--------------------------------------

             Summary: Separate default JSON metrics file locations for HS2 and 
HMS to prevent overwriting
                 Key: HIVE-29787
                 URL: https://issues.apache.org/jira/browse/HIVE-29787
             Project: Hive
          Issue Type: Improvement
            Reporter: Raghav Aggarwal
            Assignee: Raghav Aggarwal


When both HiveServer2 and Hive Metastore are running *on the same host* with 
the _JsonFileMetricsReporter_ enabled, they experience a race condition 
resulting in telemetry/observability loss. Both processes default to writing 
their metric snapshots to the exact same file: _*/tmp/report.json*_
