Test using fs.default.name in groupby1.q may be ineffective
-----------------------------------------------------------

                 Key: HIVE-1051
                 URL: https://issues.apache.org/jira/browse/HIVE-1051
             Project: Hadoop Hive
          Issue Type: Bug
            Reporter: Paul Yang
            Priority: Minor


A test query in groupby1.q sets fs.default.name to invalidscheme:/// and then 
runs an explain. The resulting output log contains a line of the form 
invalidschme:/<user path containing /tmp/>. Because of /tmp/, the line will get 
ignored.

If the objective of the test is to verify that we see invalidscheme:/  in the 
explain, then the test is ineffective because the current diff setup will 
ignore the line. Since there isn't a good way to test this, perhaps we should 
remove the test for now.

If the objective of the test is to verify that fs.default.name can be set to 
something invalid and not throw an error during an explain, then we should 
change fs.default.name to invalidschemefile:/// to so that the line gets 
ignored even if the directory changes (HIVE-1046)
