[GitHub] [kafka] zhaohaidao opened a new pull request #9310: KAFKA-10504: It will not work to skip to InitProducerId as lastError is always null

[GitBox <gi...@apache.org>]

zhaohaidao opened a new pull request #9310:
URL: https://github.com/apache/kafka/pull/9310


   
   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.
   
   We can use abortableError to skip directly to InitProduceId. abortableError is used for recording the last abortable error.
