[jira] [Created] (DRILL-3022) Ensure sequential shutdown of Drillbits

Hanifi Gunes created DRILL-3022:
-----------------------------------

             Summary: Ensure sequential shutdown of Drillbits
                 Key: DRILL-3022
                 URL: https://issues.apache.org/jira/browse/DRILL-3022
             Project: Apache Drill
          Issue Type: Bug
          Components: Tools, Build & Test
    Affects Versions: 0.9.0
            Reporter: Hanifi Gunes
            Assignee: Hanifi Gunes


When we run multiple bits within a JVM, shutting down bits might cause a race condition due to concurrent access to static MetricRegistry instance. This causes ugly error messages show up in the terminal. The proposal is to serialize shutdown of each bit via use of a global lock.
