Summary: BrokerProxy will stuck in infinite loop if consumer.fetch
throws OOME
Key: SAMZA-736
URL: https://issues.apache.org/jira/browse/SAMZA-736
Project: Samza
Issue Type: Bug
Reporter: Yi Pan (Data Infrastructure)
In BrokerProxy code, we are re-trying on exceptions from consumer fetch in an
infinite loop. However, when there is OOME thrown from consumer fetch that can
not be resolved, the container will stuck forever.
It is useful to:
1) Categorize the type of exceptions that the BrokerProxy can not recover and
fail the container
Or 2) Set an upper bound of retry on "hard" exceptions (e.g. OOME) and fail the
container when the upper bound is reached
