> This JIRA is a subtask of hdfs asynchronous router
[[HDFS-17531](https://issues.apache.org/jira/browse/HDFS-17531)].
@KeeProMise , we usually create HADOOP JIRAs and then link them to
HDFS-17531 instead of creating them as HDFS subtasks. If there are many HADOOP
JIRAs, we may create an umbrella HADOOP JIRA and then link the umbrella JIRA.

> h3. Description
> In the implementation of asynchronous Ipc.client, the main methods used
> include HADOOP-13226, HDFS-10224, etc.
> However, the existing implementation does not support `CompletableFuture`;
> instead, it relies on setting up callbacks, which can lead to the "callback
> hell" problem. Using `CompletableFuture` can better organize asynchronous
> callbacks. Therefore, on the basis of the existing implementation, by using
> `CompletableFuture`, once the `client.call` is completed, the asynchronous
> thread handles the response of this call without blocking the main thread.
