[jira] [Created] (KAFKA-8040) Streams needs to retry initTransactions

John Roesler created KAFKA-8040:
-----------------------------------

             Summary: Streams needs to retry initTransactions

    Affects Versions: 2.0.0, 2.0.1, 2.1.0, 2.2.0, 2.1.1
            Reporter: John Roesler

Following on KAFKA-7763, Streams needs to handle the new behavior.

Streams code (StreamTask.java) needs to be modified to handle the new exception.

Also, from another upstream change, `initTxn` can also throw TimeoutException now: default `MAX_BLOCK_MS_CONFIG` in producer is 60 seconds, so I think just wrapping it as StreamsException should be reasonable, similar to what we do for `producer#send`'s TimeoutException ([https://github.com/apache/kafka/blob/trunk/streams/src/main/java/org/apache/kafka/streams/processor/internals/RecordCollectorImpl.java#L220-L225] ).

 

Note we need to handle in three functions: init/commit/abortTxn.
