Hi Jayush, you are right there won't be any automatic inheritance but I don't
think that's really a bad thing. You can still have explicit inheritance with
code like this:
SCRIPT_DIR = os.path.dirname(os.path.abspath(__file__))
PARENT_DIR = os.path.join(SCRIPT_DIR, '../../../2.2/services/YARN/')
PARENT_FILE = os.path.join(PARENT_DIR, 'service_advisor.py')
try:
with open(PARENT_FILE, 'rb') as fp:
service_advisor = imp.load_module('service_advisor', fp, PARENT_FILE,
('.py', 'rb', imp.PY_SOURCE))
except Exception as e:
traceback.print_exc()
print "Failed to load parent"
class
HDP23MAPREDUCE2ServiceAdvisor(service_advisor.HDP22MAPREDUCE2ServiceAdvisor):
