> Compatibility Benchmark over HCFS Implementations
> -------------------------------------------------
>
> Key: HADOOP-19085
> URL: https://issues.apache.org/jira/browse/HADOOP-19085
> Project: Hadoop Common
> Issue Type: New Feature
> Reporter: Han Liu
> Assignee: Han Liu
> Priority: Major
> Labels: pull-request-available
> Attachments: HDFS Compatibility Benchmark Design.pdf
>
>
> {*}Background：{*}Hadoop-Compatible File System (HCFS) is a core conception in
> big data storage ecosystem, providing unified interfaces and generally clear
> semantics, and has become the de-factor standard for industry storage systems
> to follow and conform with. 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. Thanks in advance.
