Attachment: HIVE-13840.2.patch

In the updated patch
1) Another file system call in split generation is avoided by specifying max 
length in reader. If max length is not specified ORC reader will issue 
fs.getFileStatus(path) to find the length of the file.
2) Added file system stats to MockFS which is used in the newly added test case

fyi.. [~rajesh.balamohan],[~ashutoshc]

[~owen.omalley] Can you please review the patch?
