-----------------------------------
Epic Link: HDDS-13681
> [Docs] List ofs supported operations
> ------------------------------------
>
> Key: HDDS-13409
> URL: https://issues.apache.org/jira/browse/HDDS-13409
> Project: Apache Ozone
> Issue Type: Task
> Components: documentation
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.1.0
>
>
> Unlike httpsfs user doc
> https://ozone.apache.org/docs/edge/interface/httpfs.html we don't list the
> supported operation for Ofs.
> Add a table in the "Ofs (Hadoop compatible)" page for supported operations.
> The table is to have columns "Operation", "Description", "Support" where
> "Operation" is the exact operation name in the audit log, "Description" is a
> few words of short description, and "Support" is either Supported or
> Unsupported. Add footnotes for any caveats.
> To identify support status, check out the Hadoop FileSystem API source code
> (https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java).
> An API is unsupported by Ofs if the FileSystem API throws
> UnsupportedOperationException by default, and BasicRootedOzoneFileSystem and
> RootedOzoneFileSystem does not implement or throws
> UnsupportedOperationException.
> add another table for HDFS specific operations that is not in Hadoop
> FileSystem API, and thus unsupported by Ofs. Use HDFS
> DistributedFileSystem.java as source of truth:
> https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DistributedFileSystem.java
> Write down your execution plan to confirm with me before proceeding further.
> ---
> For every row in the Supported Operations table, make sure it is a public
> method in BasicRootedOzoneFileSystem or
> RootedOzoneFileSystem. Are there any public method in
> BasicRootedOzoneFileSystem or RootedOzoneFileSystem that is not listed?
> Check if these public methods asicRootedOzoneFileSystem or
> RootedOzoneFileSystem also exist in FileSystem API. If so, add them to the
> table.
