Steve Loughran updated HADOOP-9371:
-----------------------------------
Attachment: HadoopFilesystemContract.pdf
This is my initial draft of an FS contract, written while implementing and
testing HADOOP-8545. It is a google docs document: a full patch would
# define the core requirements in a document (package javadocs or site file)
# add the requirements of each method in the javadocs of that method.
> Define Semantics of FileSystem and FileContext more rigorously
> --------------------------------------------------------------
>
> Key: HADOOP-9371
> URL: https://issues.apache.org/jira/browse/HADOOP-9371
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs
> Affects Versions: 1.2.0, 3.0.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Attachments: HadoopFilesystemContract.pdf
>
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> The semantics of {{FileSystem}} and {{FileContext}} are not completely
> defined in terms of
> # core expectations of a filesystem
> # consistency requirements.
> # concurrency requirements.
> # minimum scale limits
> Furthermore, methods are not defined strictly enough in terms of their
> outcomes and failure modes.
> The requirements and method semantics should be defined more strictly.
