I set the workdir, but the launch directory still generated the ignite directory.

I set the workdir, but the launch directory still generated the ignite directory.
`
IgniteConfiguration igniteConfiguration = new IgniteConfiguration(); igniteConfiguration.setAsyncCallbackPoolSize(Runtime.getRuntime().availableProcessors() / 2); igniteConfiguration.setWorkDirectory(System.getProperty("user.home") + "/data");

`

Did the set workdir not take effect? What does this file mean?

It works as expected for me with Ignite 2.16:

package org.example;

import org.apache.ignite.Ignition;
import org.apache.ignite.configuration.IgniteConfiguration;

public class Main {
    public static void main(String[] args) {
        IgniteConfiguration igniteConfiguration = new IgniteConfiguration();
        igniteConfiguration.setWorkDirectory(System.getProperty("user.home") + "/w/tests/ignite-work");

        Ignition.start(igniteConfiguration);
    }
}

 pavel > work > w > tests > ignite-work $ ls -la --recursive

I am also using version 2.16, JDK 21, and a cluster deployment method with a total of 3 nodes. The data mainly consists of some external data sources and some in memory data sources. No problem found

The diagnostic directory I specified is empty, but there are data files in the ignote directory of the startup directory
