Subject [jira] [Created] (HADOOP-13051) Test for special characters in path being respected during globPaths

Harsh J created HADOOP-13051:
--------------------------------

             Summary: Test for special characters in path being respected during globPaths
                 Key: HADOOP-13051
                 URL: https://issues.apache.org/jira/browse/HADOOP-13051
             Project: Hadoop Common
          Issue Type: Test
          Components: fs
    Affects Versions: 3.0.0
            Reporter: Harsh J
            Assignee: Harsh J
            Priority: Minor


On {{branch-2}}, the below is the (incorrect) behaviour today, where paths with special characters
get dropped during globStatus calls:

{code}
bin/hdfs dfs -mkdir /foo
bin/hdfs dfs -touchz /foo/foo1
bin/hdfs dfs -touchz $'/foo/foo1\r'
bin/hdfs dfs -ls '/foo/*'
-rw-r--r--   3 harsh supergroup          0 2016-04-22 17:35 /foo/foo1
-rw-r--r--   3 harsh supergroup          0 2016-04-22 17:35 /foo/foo1^M
bin/hdfs dfs -ls '/foo/*'
-rw-r--r--   3 harsh supergroup          0 2016-04-22 17:35 /foo/foo1
{code}

Whereas trunk has the right behaviour, subtly fixed via the pattern library change of HADOOP-12436:

{code}
bin/hdfs dfs -mkdir /foo
bin/hdfs dfs -touchz /foo/foo1
bin/hdfs dfs -touchz $'/foo/foo1\r'
bin/hdfs dfs -ls '/foo/*'
-rw-r--r--   3 harsh supergroup          0 2016-04-22 17:35 /foo/foo1
-rw-r--r--   3 harsh supergroup          0 2016-04-22 17:35 /foo/foo1^M
bin/hdfs dfs -ls '/foo/*'
-rw-r--r--   3 harsh supergroup          0 2016-04-22 17:35 /foo/foo1
-rw-r--r--   3 harsh supergroup          0 2016-04-22 17:35 /foo/foo1^M
{code}

(I've placed a ^M explicitly to indicate presence of the intentional hidden character)

We should still add a simple test-case to cover this situation for future regressions.
