Description
There is a route compatibility layer between 0.7 and 0.9 for /tez-app/ -> /app/. However, sub-routes like /tez-app/<app id>/dags and /tez-app/<app id>/configs don't work.
In addition the all dags query params have changed between 0.7 and 0.9.
appid -> appID
dag_name -> dagName
id -> dagID
user -> submitter
This jira should address adding or extending the compatibility layer so the transition from 0.7 to 0.9 is more seamless.
