John Blum updated GEODE-8286: ----------------------------- Issue Type: Bug (was: Improvement) > The Geode JVM Shutdown Hook should not be enabled by default > ------------------------------------------------------------ > > Key: GEODE-8286 > URL: https://issues.apache.org/jira/browse/GEODE-8286 > Project: Geode > Issue Type: Bug > Components: configuration, general, management > Reporter: John Blum > Priority: Critical > Labels: JSON-PDX > > Apache Geode registers a JVM Shutdown Hook in > [InternalDistributedSystem|https://github.com/apache/geode/blob/rel/v1.12.0/geode-core/src/main/java/org/apache/geode/distributed/internal/InternalDistributedSystem.java#L2190-L2222] > that ensures the Apache Geode Cache and associated DistributedSystem are > shutdown properly when the JVM exits. > However, this JVM Shutdown Hook and interfere with Frameworks and Tooling > that have their own Lifecycle Management capabilities. The Spring Framework > and Container is one such example. > Any managed environment, be that Micronaut, Quarkus, Pivotal Platform > (PCF/TAS), Kubernetes, AWS, Azure, GCP, etc, etc, are going to have lifecycle > management capabilities. > It is very important that the environment manage the lifecycle of all actors > in the fully "integrated" system. > In Spring's case, it must coordinate the lifecycle of application components > along with integrated systems, like Geode, in an effort to shut all > components down in a coordinated, correct fashion. > If Geode's JVM Shutdown Hook is permitted to do as it pleases, then this can > circumvent the Framework/Container, Tool, or other's lifecycle management > capabilities, leaving the system or application in an inconsistent/incorrect > state. > To make matters worse, the [JVM System > Property|https://github.com/apache/geode/blob/rel/v1.12.0/geode-core/src/main/java/org/apache/geode/distributed/internal/InternalDistributedSystem.java#L2191] > (and specifically, > [this|https://github.com/apache/geode/blob/rel/v1.12.0/geode-core/src/main/java/org/apache/geode/distributed/internal/InternalDistributedSystem.java#L391-L392]) > controlling the enablement of the JVM Shutdown Hook, is non-public and [not > documented|https://geode.apache.org/docs/guide/112/reference/topics/gemfire_properties.html]. -- This message was sent by Atlassian Jira (v8.3.4#803005)
