Subject [jira] [Commented] (HADOOP-15616) Incorporate Tencent Cloud COS File System Implementation
Date Fri, 07 Dec 2018 23:26:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16713400#comment-16713400

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.



Should we put hadoop-cos under hadoop-tools project like s3a, adsl, etc. instead of hadoop-cloud-storage-project?



Line 24: Secret Key->Secret ID

Can we add more description to other keys added here to help users can configure it properly?




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.
