Aaron T. Myers commented on HADOOP-8310:
----------------------------------------
Thanks a lot for the review, John. I'm confident that the test failure of
TestViewFsTrash is unrelated.
I should also mention that I discovered this issue because without this fix one
cannot view the conf page of a running MR2 job in a cluster whose
fs.default.name is configured without a port. I manually verified that with
this fix, one can get to the page just fine.
I also ran the full HDFS test suite with this patch applied and everything
passed.
> FileContext#checkPath should handle URIs with no port

> AbstractFileSystem#checkPath is used to verify that a given path is for the
> same file system as represented by the AbstractFileSystem instance.
> The original intent of the code was to allow for no port to be provided in
> the checked path, if the default port was being used by the
> AbstractFileSystem instance. However, before performing port handling,
> AFS#checkPath compares the full URI authorities for equality. Since the URI
> authority includes the port, the port handling code is never reached, and
> thus valid paths may be erroneously considered invalid.
