----------------------------------
hi steve progress looks great. Have started some on both HADOOP-10463 and
HADOOP-10461 which i think both will be able to leverage the declarative part
that this adds.
- What did you mean "doesnt compile remotely" ? Let me know if i can lend a
hand with anything. looks like tests are failing but compilation works.
- let me know if i can lend a hand anywhere :)
> Strictly define the expected behavior of filesystem APIs and write tests to
> verify compliance

> {{FileSystem}} and {{FileContract}} aren't tested rigorously enough -while
> HDFS gets tested downstream, other filesystems, such as blobstore bindings,
> don't.
> The only tests that are common are those of {{FileSystemContractTestBase}},
> which HADOOP-9258 shows is incomplete.
> I propose
> # writing more tests which clarify expected behavior
> # testing operations in the interface being in their own JUnit4 test classes,
> instead of one big test suite.
> # Having each FS declare via a properties file what behaviors they offer,
> such as atomic-rename, atomic-delete, umask, immediate-consistency -test
> methods can downgrade to skipped test cases if a feature is missing.
