Review Comment:
We should use static imports instead of named imports.
> Integration of Volcano Engine TOS in Hadoop.
> --------------------------------------------
>
> Key: HADOOP-19236
> URL: https://issues.apache.org/jira/browse/HADOOP-19236
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs, tools
> Affects Versions: 3.4.0
> Reporter: Jinglun
> Assignee: Zheng Hu
> Priority: Major
> Labels: pull-request-available
> Attachments: Integration of Volcano Engine TOS in Hadoop.pdf
>
>
> Volcano Engine is a fast growing cloud vendor launched by ByteDance, and TOS
> is the object storage service of Volcano Engine. A common way is to store
> data into TOS and run Hadoop/Spark/Flink applications to access TOS. But
> there is no original support for TOS in hadoop, thus it is not easy for users
> to build their Big Data System based on TOS.
>
> This work aims to integrate TOS with Hadoop to help users run their
> applications on TOS. Users only need to do some simple configuration, then
> their applications can read/write TOS without any code change. This work is
> similar to AWS S3, AzureBlob, AliyunOSS, Tencnet COS and HuaweiCloud Object
> Storage in Hadoop.
>
> Please see the attached document "Integration of Volcano Engine TOS in
> Hadoop" for more details.
