There have been a series of HCFS implementations > in Hadoop, such as S3AFileSystem for Amazon's S3 Object Store, WASB for > Microsoft's Azure Blob Storage and OSS connector for Alibaba Cloud Object > Storage, and more from storage service's providers on their own. > {*}Problems:{*}However, as indicated by introduction.md, there is no formal > suite to do compatibility assessment of a file system for all such HCFS > implementations. Thus, whether the functionality is well accomplished and > meets the core compatible expectations mainly relies on service provider's > own report. Meanwhile, Hadoop is also developing and new features are > continuously contributing to HCFS interfaces for existing implementations to > follow and update, in which case, Hadoop also needs a tool to quickly assess > if these features are supported or not for a specific HCFS implementation. > Besides, the known hadoop command line tool or hdfs shell is used to directly > interact with a HCFS storage system, where most commands correspond to > specific HCFS interfaces and work well. Still, there are cases that are > complicated and may not work, like expunge command. To check such commands > for an HCFS, we also need an approach to figure them out. > {*}Proposal:{*}Accordingly, we propose to define a formal HCFS compatibility > benchmark and provide corresponding tool to do the compatibility assessment > for an HCFS storage system. The benchmark and tool should consider both HCFS > interfaces and hdfs shell commands. Different scenarios require different > kinds of compatibilities. For such consideration, we could define different > suites in the benchmark. > *Benefits:* We intend the benchmark and tool to be useful for both storage > providers and storage users. For end users, it can be used to evalute the > compatibility level and determine if the storage system in question is > suitable for the required scenarios. For storage providers, it helps to > quickly generate an objective and reliable report about core functioins of > the storage service. As an instance, if the HCFS got a 100% on a suite named > 'tpcds', it is demonstrated that all functions needed by a tpcds program have > been well achieved. It is also a guide indicating how storage service > abilities can map to HCFS interfaces, such as storage class on S3. > Any thoughts? Comments and feedback are mostly welcomed.
