-----------------------------
Summary: customer ‘rest.bind-address' config overwrite by code
Key: FLINK-35747
URL: https://issues.apache.org/jira/browse/FLINK-35747
Project: Flink
Issue Type: Bug
Components: Deployment / YARN
Affects Versions: 1.19.1
Reporter: dncba
When I want flink on Yarn webui bind on 0.0.0.0 to listen Ipv4 & Ipv6 double
stack, I found the ‘rest.bind-address' config will auto overwrite by here
{code:java}
package org.apache.flink.yarn.entrypoint;
````
public class YarnEntrypointUtils {
````
public static Configuration loadConfiguration(
final Configuration configuration =
GlobalConfiguration.loadConfiguration(workingDirectory,
dynamicParameters);
final String hostname
=env.get(ApplicationConstants.Environment.NM_HOST.key());
configuration.set(JobManagerOptions.ADDRESS, hostname);
configuration.set(RestOptions.ADDRESS, hostname);
# overwrite hostname by code
configuration.set(RestOptions.BIND_ADDRESS, hostname);
`````
}
}
{code}
In most case the are right. when user want config the ‘rest.bind-address' by
slef , the customer config will be auto overwirte.
the best way is check the user config before the ovewrite. like this
{code:java}
public class YarnEntrypointUtils {
````
public static Configuration loadConfiguration(
final Configuration configuration =
GlobalConfiguration.loadConfiguration(workingDirectory,
dynamicParameters);
final String hostname
=env.get(ApplicationConstants.Environment.NM_HOST.key());
configuration.set(JobManagerOptions.ADDRESS, hostname);
configuration.set(RestOptions.ADDRESS, hostname);
# check before the overwrite
String bindAddress = configuration.getString(RestOptions.BIND_ADDRESS);
if (StringUtils.isBlank(bindAddress)) {
configuration.setString(RestOptions.BIND_ADDRESS, hostname);
}
`````
}
}
{code}
