Subject [jira] [Commented] (HADOOP-13104) Document meaning of all file system contract options used in the contract tests.
Date Fri, 06 May 2016 16:01:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15274266#comment-15274266

Chris Nauroth commented on HADOOP-13104:
----------------------------------------

[~stevel@apache.org], are you saying that you disagree with putting them public on the site?
 If so, then maybe this JIRA takes a different form, like a higher level description of differences
in semantics across the file system implementations, and the contract options remain a private
detail for the devs.

> The file system contract tests support a set of contract options.  Each file system's
specific test suite subclasses may set these options, and they alter the behavior of the tests
to account for the inevitable differences in semantics in some implementations.  The {{ContractOptions}}
interface already has JavaDocs describing the behavior of the options.  This issue proposes
propagating similar documentation up to the public site.  This also will be valuable as a
source of information for understanding differences in semantics at a high level, i.e. POSIX
vs. HDFS vs. S3A.
