StefanRRichter commented on issue #6739: [FLINK-10289] [JobManager] Classify 
Exceptions to different category for apply different failover strategy
URL: https://github.com/apache/flink/pull/6739#issuecomment-427281153
 
 
   @isunjin I think this looks good now. I wonder if we should rename the type 
`Other` to something like `RecoverableFailure`?

> 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.
