------------------------------------------------
Summary: Rebalances in standalone doesn't handle DAG changes for
restarted processor
Key: SAMZA-2635
URL: https://issues.apache.org/jira/browse/SAMZA-2635
Project: Samza
Issue Type: Bug
Reporter: Bharath Kumarasubramanian
Assignee: Bharath Kumarasubramanian
*Problem*: In the current standalone zookeeper mode, we don't handle the
scenario where an incoming processor can have DAG changes or application
changes that render the job model generated by the leader invalid.
Reasons that this could happen is
# Leader runs on older version of the application
# Optimization introduced as part of SAMZA-2633 which starts the processor w/
the most recent active job model version (this just increases the chances of
the above problem)
