Work Description: sunchao opened a new pull request #2510:
URL: https://github.com/apache/hadoop/pull/2510
This removes `ListenableFuture` as well as `ListeningExecutorService` from
`SemaphoredDelegatingExecutor`, so that `hadoop-aws` as well as `hadoop-aliyun`
can consume it from `hadoop-client-api`.

> I attempted to use Accumulo and S3a with the following jars on the classpath.
> * hadoop-client-api-3.1.1.jar
> * hadoop-client-runtime-3.1.1.jar
> * hadoop-aws-3.1.1.jar
> This failed with the following exception.
> {noformat}
> Exception in thread "init" java.lang.NoSuchMethodError:

> The problem is that {{S3AFileSystem.create()}} looks for
> {{SemaphoredDelegatingExecutor(com.google.common.util.concurrent.ListeningExecutorService)}}
> which does not exist in hadoop-client-api-3.1.1.jar. What does exist is
> {{SemaphoredDelegatingExecutor(org.apache.hadoop.shaded.com.google.common.util.concurrent.ListeningExecutorService)}}.
> To work around this issue I created a version of hadoop-aws-3.1.1.jar that
> relocated references to Guava.
