Fixed with this code

+# encoding=utf8
 +
  import sys, os, pwd, grp, signal, time, glob  import sys, os, pwd, grp, signal, time, glob
  from resource_management import *  from resource_management import *
  from subprocess import call  from subprocess import call

 +reload(sys)
 +sys.setdefaultencoding('utf8')

Python's default encoding is ASCII which throws UnicodeDecodeError when trying to decode a stream/array of bytes to Unicode. Setting the default encoding to UTF-8 will fix the conversion from bytes to UTF-8 encoded string.
