[~yuyang733] [~Sammi] I think you should remove Chinese comments from 010.patch.
{code:java}
// code placeholder
+ this.blockCacheBuffers.add(this.currentBlockBuffer);
+ // 加到块列表中去
+ if (this.blockCacheBuffers.size() == 1) {
+ // 单个文件就可以上传完成
+ byte[] md5Hash = this.digest == null ? null : this.digest.digest();

> Tencent cloud is top 2 cloud vendors in China market and the object store COS （[https://intl.cloud.tencent.com/product/cos]） is widely used among China’s cloud users but now it is hard for hadoop user to access data laid on COS storage as no native support for COS in Hadoop.
> This work aims to integrate Tencent cloud COS with Hadoop/Spark/Hive, just like what we do before for S3, ADL, OSS, etc. With simple configuration, Hadoop applications can read/write data from COS without any code change.
