-------------------------------
Summary: Define the completeness of VertexManager
Key: TEZ-2589
URL: https://issues.apache.org/jira/browse/TEZ-2589
Project: Apache Tez
Issue Type: Sub-task
Reporter: Jeff Zhang
Assignee: Jeff Zhang
VertexManager may interact with Vertex with the whole lifecycle of Vertex. This
make the recovery of Vertex pretty complicated. The recovery of Vertex depends
on the recovery of VertexManager. And the recovery of VertexManager is almost
of impossible, because it is user-facing API, we don't have control on that.
Define the completeness could help the recovery of Vertex. The completeness of
VertexManager means it has complete its responsibility and won't interact with
Vertex again which means it won't affect the recovery of vertex from now on.
