-----------------------------------
Summary: Improve PhoenxiDriver registration when addShutdownHook
fails
Key: PHOENIX-1976
URL: https://issues.apache.org/jira/browse/PHOENIX-1976
Project: Phoenix
Issue Type: Bug
Reporter: Josh Elser
Priority: Minor
Fix For: 4.5.0
Noticed this in running some tests. RegionServer was shutting down and
MetaDataRegionObserver was just invoking {{postOpen}}
When the {{Class.forName(PhoenixDriver.class.getName())}} gets called, the
static initializer in {{PhoenixDriver}} gets invoked. Because the RegionServer
is already stopping, the {{addShutdownHook}} fails with an
{{IllegalArgumentException}}.
It's not a _huge_ concern because we know the JVM is going down, but there are
a few things we could handle better:
* Ensure the PhoenixDriver gets closed if the shutdown hook fails to register
* Avoid registering the PhoenixDriver instance if we're shutting down
