> [ARR]: AsyncUtil makes asynchronous code more concise and easier.
> -----------------------------------------------------------------
>
>                 Key: HDFS-17543
>                 URL: https://issues.apache.org/jira/browse/HDFS-17543
>             Project: Hadoop HDFS
>          Issue Type: Sub-task
>            Reporter: Jian Zhang
>            Assignee: Jian Zhang
>            Priority: Major
>              Labels: pull-request-available
>
> *Describe*
> Using the original Java CompletableFuture to implement an asynchronous router 
> is not conducive to the development of the open source community due to poor 
> code readability and maintainability. Therefore, I have implemented a 
> lightweight tool that encapsulates CompletableFuture.
> By using this AsyncUtil, it is easy to write readable asynchronous code, 
> which is easy for everyone to understand. I have provided an example of this 
> tool class in UT, demonstrating how to change synchronous methods to 
> asynchronous code.
>  
> *Examples and tests*
> SyncClass provides some common synchronization methods
> AsyncClass is the corresponding asynchronous implementation
> Use TestAsyncUtil to simultaneously test the methods corresponding to 
> SyncClass and AsyncClass, ensuring that both asynchronous and synchronous 
> methods return the same results
>  
> {*}NOTE{*}: In HDFS-17545, I used this tool to implement RouterAsyncRpcClient 
> which extends RouterRpcClient.  You can also view RouterAsyncRpcClient to 
> understand the use of this tool.
