------------------------------------
Hi [~decster] and [~andrew.wang], this change has caused a regression for Pig.

> decster:~/hadoop> bin/hadoop fs -ls "/foo/.snapshot"
> 13/08/16 01:17:22 INFO hdfs.DFSClient: +++++ listPath(/)
> 13/08/16 01:17:22 INFO hdfs.DFSClient: +++++ listPath(/foo)
> ls: `/foo/.snapshot': No such file or directory
> {code}
> HADOOP-9817 refactor some globStatus code, but forgot to handle special case
> that .snapshot dir is not show up in listStatus but exists, so we need to
> explicitly check path existence using getFileStatus, rather than depending on
> listStatus results.
