Subject [jira] [Commented] (HADOOP-13104) Document meaning of all file system contract options used in the contract tests.
Date Tue, 10 May 2016 12:54:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15278040#comment-15278040

Steve Loughran commented on HADOOP-13104:

Nothing against making the values public, and we could even enumerate the differences. It's
a different question as to whether and how to make those differences known. Someone —Sanjay?
Suresh? wanted the XML files to be in the test/resources tree for that reason: to keep the
details private

> 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.
