["Aaron Kimball (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-5901?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aaron Kimball updated HADOOP-5901:
----------------------------------

    Attachment: HADOOP-5901.patch

Attaching a patch which removes {{fixName}} and adds {{checkName}} in its place. Added unit tests that check a variety of potential default fs URLs and make sure that {{FileSystem.get()}} still returns something reasonable (e.g., the FileSystem associated with the {{DEFAULT_FS}} URI).

The aforementioned stack overflow is prevented by this patch.

Locally, I get the following from test-patch:
{code}
     [exec] +1 overall.  
     [exec] 
     [exec]     +1 @author.  The patch does not contain any @author tags.
     [exec] 
     [exec]     +1 tests included.  The patch appears to include 3 new or modified tests.
     [exec] 
     [exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
     [exec] 
     [exec]     +1 javac.  The applied patch does not increase the total number of javac compiler warnings.
     [exec] 
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs warnings.
     [exec] 
     [exec]     +1 release audit.  The applied patch does not increase the total number of release audit warnings.

> {{FileSystem.fixName()}} tries to patch up fs.default.name values, but I'm not sure it helps that well. 
> Has it been warning about deprecated values for long enough for it to be turned off?
