File "/opt/huawei/Bigdata/hue-3.5.0.tar/hue/apps/sqoop/src/sqoop/api/exception.py", line 31, in handle_rest_exception

suggestion:
replace the line 31 in hue/apps/sqoop/src/sqoop/api/exception.py with following code:

  parent_ex = e.get_parent_ex()
  reason = None
  if hasattr(parent_ex, 'reason'):
    reason = parent_ex.reason

would someone fix it please?
