Summary: Admin Service API for Stopping the Gateway
Key: KNOX-522
URL: https://issues.apache.org/jira/browse/KNOX-522
Project: Apache Knox
Issue Type: Improvement
Components: Server
Reporter: Larry McCay
We need to add a graceful way to shutdown the server that allows existing
requests to complete but doesn't accept to connections before it actually stops.
See the embedded Jetty APIs for setting the options:
server.setGracefulShutdown(millis);
server.setStopAtShutdown(true);
The millis provided in the setGracefulShutdown indicates the graceperiod to
allow existing requests to complete before killing them.
The setStopAtShutdown boolean enables or disables the grace period.
This improvement will be useful in rolling upgrade scenarios where a number of
instances are running and we want to cycle one after another without disrupting
requests being processed.
