          I poked around to debug the failing test. It turns out we have some FC only code in TestGlobPaths#TestGlobFillsInScheme:

                if (fc != null) {
                  // If we're using FileContext, then we can list a file:/// URI.
                  // Since everyone should have the root directory, we list that.
                  statuses = wrap.globStatus(new Path("file:///"),
                      new AcceptAllPathFilter());
                  Assert.assertEquals(1, statuses.length);
                  Path filePath = statuses[0].getPath();
                  Assert.assertEquals("file", filePath.toUri().getScheme());
                  Assert.assertEquals("/", filePath.toUri().getPath());
                }
          

          The tricky part here is that the default filesystem for this FileContext is an HDFS, which is why Jenkins is picking up "localhost:port" for the authority in Globber#authorityFromPath:

                  authority = fc.getDefaultFileSystem().getUri().getAuthority();
          

          If I change it to this, the test passes:

                  authority = fc.getFSofPath(path).getUri().getAuthority();
          

          I think the error stems from how file:// URIs have a null authority, and we shouldn't fill it in. I think the fix is to use getFSofPath for both FC and FS in authorityFromPath.

          Thanks to Aaron T. Myers for figuring out that this is the globber after all. It turns out that there is a bug which causes the Globber to return a bogus FileStatus when asked about root. This doesn't affect what I was testing (i.e. that we can chmod or chown the root directory).

          So during my test, the root was actually being modified, but I just couldn't see it because the globber continued to tell me that it had the same status as before. atm wrote a program which bypassed the globber and proved that the inode was being modified after all.

          I don't see what this has to do with the globber. The globber can resolve the root inode just fine.

          In fact, there's a unit test for this in TestGlobPaths:

              Path root = new Path(USER_DIR);
              status = fs.globStatus(root);
              checkStatus(status, root);
          

          The problem is not on the client side. I ran a "chmod /" and traced it back all the way to the FSNamesystem, which seems to be calling FSDirectory#setPermission on src=(empty string). Then FSDirectory#unprotectedSetPermission locates the root inode and calls INode#setPermission on it. For some reason, that doesn't work / take effect.

          There seems to be a more general problem where modifying the root inode fails. I can't change the owner or group, for example. The INode stuff has been modified a lot over the last few releases. The inclusion of snapshots, the Feature work, and probably some other stuff I'm forgetting. I think someone needs to go in there and do a deep dive to fix this.

          By the way, I verified that I could chmod / chown snapshottable directories. I was a little concerned about that after looking at this problem. But the issue seems to be specific to root.
