+1 the new changes look fine to me. I am not so sure about HBOCodeLabs#4
It should be fine, I'm just not super thrilled about changing static methods to
be instance methods for mocking purposes. I don't know of a better way to do
it, so please through up a pull request and we can discuss it.
> Add delayed retries to KafkaSpout
> ---------------------------------
>
> Key: STORM-495
> URL: https://issues.apache.org/jira/browse/STORM-495
> Project: Apache Storm
> Issue Type: Improvement
> Affects Versions: 0.9.3
> Environment: all environments
> Reporter: Rick Kilgore
> Priority: Minor
> Labels: kafka, retry
>
> If a tuple in the topology originates from the KafkaSpout from the
> external/storm-kafka sources, and if a bolt in the topology indicates a
> failure by calling fail() on its OutputCollector, the KafkaSpout will
> immediately retry the message.
> We wish to use this failure and retry behavior in our ingestion system
> whenever we experience a recoverable error from a downstream system, such as
> a 500 or 503 error from a service we depend on. But with the current
> KafkaSpout behavior, doing so results in a tight loop where we retry several
> times over a few seconds and then give up. I want to be able to delay retry
> to give the downstream service some time to recover. Ideally, I would like
> to have configurable, exponential backoff retry.
