---------------------------------
Summary: Support broadcast edge into cartesian product vertex and
forbid other edges
Key: TEZ-3465
URL: https://issues.apache.org/jira/browse/TEZ-3465
Project: Apache Tez
Issue Type: Sub-task
Reporter: Zhiyuan Yang
Assignee: Zhiyuan Yang
Cartesian product vertex manager should support other incoming edge type.
Currently only broadcast edge is necessary, although potentially more edge
types could also be. Custom edge need its own vertex manager which can't work
with Cartesian product VM, so it has to be forbade.
