Ming Ma commented on TEZ-3230:
------------------------------
About "Only on demand routing" question, I am trying to understand this. It
seems only CDME is used in the current design. Do you know when will DME be
used or it is legacy? If IIUC, in {{Edge#maybeAddTezEventForDestinationTask}}'s
function that handles {{EdgeManagerPluginOnDemand}}, it supports both CDME and
CME. In other words, it appears on demand routing is independent of whether it
is CDME and DME. If that is true, maybe the message should be "Only CDME is
supported".
