Xiaoyu Yao commented on HADOOP-15616:
-------------------------------------
[~yuyang733], thanks for working on this. I took a brief look at the v5 patch.
Here are a few issues, more will be added next week once I finish reviewing it.
NIT: changes under hadoop-tools/hadoop-aliyun are unrelated.
Hadoop-cloud-storage-project/pom.xml
Should we put hadoop-cos under hadoop-tools project like s3a, adsl, etc.
instead of hadoop-cloud-storage-project?
core-site.xml
Line 24: Secret Key->Secret ID
Can we add more description to other keys added here to help users can
configure it properly?
BufferPool.java
Line 181: since it sets the disk buffer file delete on exist, does it support
recovery if client restart?

> 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.
