-------------------------------
Summary: InputReadyVertexManager not resilient to updates in
parallelism
Key: TEZ-2011
URL: https://issues.apache.org/jira/browse/TEZ-2011
Project: Apache Tez
Issue Type: Bug
Reporter: Bikas Saha
Assignee: Bikas Saha
It sets up its internal book-keeping upon onVertexStarted() but that
book-keeping can be wrong if its parallelism changes after that. It needs to
subscribe to Vertex configured event for its source vertices to make sure that
all changes have been made before initializing its internal state.
