>
> We need to classify exceptions and treat them with different strategies. To
> do this, we propose to introduce the following Throwable Types, and the
> corresponding exceptions:
> * NonRecoverable
> ** We shouldn’t retry if an exception was classified as NonRecoverable
> ** For example, NoResouceAvailiableException is a NonRecoverable Exception
> ** Introduce a new Exception UserCodeException to wrap all exceptions that
> throw from user code
> * PartitionDataMissingError
> ** In certain scenarios producer data was transferred in blocking mode or
> data was saved in persistent store. If the partition was missing, we need to
> revoke/rerun the produce task to regenerate the data.
> ** Introduce a new exception PartitionDataMissingException to wrap all those
> kinds of issues.
> * EnvironmentError
> ** It happened due to hardware, or software issues that were related to
> specific environments. The assumption is that a task will succeed if we run
> it in a different environment, and other task run in this bad environment
> will very likely fail. If multiple task failures in the same machine due to
> EnvironmentError, we need to consider adding the bad machine to blacklist,
> and avoiding schedule task on it.
> ** Introduce a new exception EnvironmentException to wrap all those kind of
> issues.
> * Recoverable
> ** We assume other issues are recoverable.
