-------------------------------
Summary: Generalize change in connected vertices when the
parallelism of a vertex changes
Key: TEZ-1059
URL: https://issues.apache.org/jira/browse/TEZ-1059
Project: Apache Tez
Issue Type: Task
Reporter: Bikas Saha
Assignee: Bikas Saha
When a vertex changes its parallelism, consumer vertices may need to respond to
it. 1-1 consumer vertices would need to change their parallelism to match.
Scatter-gather consumers dont need to change.
Currently, the tez dag code has special cased this for 1-1 edge which is fine
for now but does not work with custom edges.
