Yi Pan (Data Infrastructure) commented on SAMZA-1361:
-----------------------------------------------------
An alternative solution to remove the operatorImpls map completely is to
traverse the StreamGraphImpl in topo-sort order. It would be nice to consider
this option as well when fixing this bug.
> OperatorImplGraph used wrong keys to store/retrieve OperatorImpl in the map

> Key: SAMZA-1361

> Project: Samza
> Issue Type: Bug
> Affects Versions: 0.13.0
> Reporter: Yi Pan (Data Infrastructure)
> Fix For: 0.13.1

> The operatorsImpls in the OperatorImplGraph is using String as the lookup
> key, while the code to put the operatorImpl is using OperatorSpec as the key.
> The key used to lookup and retrieval should be consistent.
