-----------------------------------
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.
