-----------------------------------
Summary: It will not work to skip to InitProducerId as lastError
is always null
Key: KAFKA-10504
URL: https://issues.apache.org/jira/browse/KAFKA-10504
Project: Kafka
Issue Type: Improvement
Components: clients
Reporter: HaiyuanZhao
Assignee: HaiyuanZhao
Kafka-8805 introduced an optimization for txn abort process: If the last error
is
an INVALID_PRODUCER_ID_MAPPING error, skip directly to InitProduceId.
However this optimization will not work as the var lastError is always null.
Because the txn state will transit to ABORTING_TRANSACTION from ABORTABLE_ERROR
when beginAbort is called, and the lastError will updated to null.
So then EndTxn is always called before InitProduceId.
