Yan Fang commented on SAMZA-64:
-------------------------------

Added some lines to fail the entrie SamzaContainer for InvalidMessageCode .
1) but have difficulty in writing the unit test for this. Any existing class/method to trigger this error?
2) Any other unrecoverable exceptions besides InvalidMessageCode?

> KafkaCheckpointManager currently handles all errors from Kafka by waiting, and retrying. These error codes are located in Kafka's ErrorMapping class:
> {noformat}
> val UnknownCode : Short = -1
> val NoError : Short = 0
> val OffsetOutOfRangeCode : Short = 1
> val InvalidMessageCode : Short = 2
> val UnknownTopicOrPartitionCode : Short = 3
> val InvalidFetchSizeCode  : Short = 4
> val LeaderNotAvailableCode : Short = 5
> val NotLeaderForPartitionCode : Short = 6
> val RequestTimedOutCode: Short = 7
> val BrokerNotAvailableCode: Short = 8
> val ReplicaNotAvailableCode: Short = 9
> val MessageSizeTooLargeCode: Short = 10
> val StaleControllerEpochCode: Short = 11
> {noformat}
> There was some discussion on SAMZA-62's RB about potentially not retrying on ALL errors. Some are not recoverable (e.g. InvalidMessageCode).
