[jira] [Created] (HADOOP-19235) IPC client uses CompletableFuture to support asynchronous operations.

Jian Zhang created HADOOP-19235:
-----------------------------------

             Summary: IPC client uses CompletableFuture to support asynchronous operations.
                 Key: HADOOP-19235
                 URL: https://issues.apache.org/jira/browse/HADOOP-19235
             Project: Hadoop Common
          Issue Type: New Feature
          Components: common
            Reporter: Jian Zhang


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.
