----------------------------------
Summary: Support override of configuration annotations
Key: HDDS-1747
URL: https://issues.apache.org/jira/browse/HDDS-1747
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Elek, Marton
Assignee: Stephen O'Donnell
To support HDDS-1744 we need a way to override existing configuration defaults.
For example given a main HttpConfiguration:
{code:java}
public class OzoneHttpServerConfig {
private int httpBindPort;
@Config(key = "http-bind-port",
defaultValue = "9874",
description =
"The actual port the web server will listen on for HTTP "
+ "communication. If the "
+ "port is 0 then the server will start on a free port.",
tags = {ConfigTag.OM, ConfigTag.MANAGEMENT})
public void setHttpBindPort(int httpBindPort) {
this.httpBindPort = httpBindPort;
}
{code}
We need an option to extend this class and override the default value:
{code:java}
@ConfigGroup(prefix = "hdds.datanode")
public static class HttpConfig extends OzoneHttpServerConfig {
@Override
@ConfigOverride(defaultValue = "9882")
public void setHttpBindPort(int httpBindPort) {
super.setHttpBindPort(httpBindPort);
}
}
{code}
The expected behavior is a generated hdds.datanode.http-bind-port where the
default is 9882.
