> 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.
