Ming Ma commented on TEZ-3230:
------------------------------
bq. For now, cDME is more prevalent given it won't consume too much memory, so
I optimize for cDME only
Does it mean the TezException message "Only on demand routing ..." needs to be
changed?
bq. memory is rarer resource than CPU
But the existing taskIdMapping can be replaced by the new
taskIdToPartitionMapping?
> Implement vertex manager and edge manager of cartesian product edge
