> Introduce sasl retry count in RetryingBlockTransferor
> -----------------------------------------------------
>
> Key: SPARK-42090
> URL: https://issues.apache.org/jira/browse/SPARK-42090
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.4.0
> Reporter: Ted Yu
> Assignee: Ted Yu
> Priority: Major
> Fix For: 3.4.0
>
>
> Previously a boolean variable, saslTimeoutSeen, was used in
> RetryingBlockTransferor. However, the boolean variable wouldn't cover the
> following scenario:
> 1. SaslTimeoutException
> 2. IOException
> 3. SaslTimeoutException
> 4. IOException
> Even though IOException at #2 is retried (resulting in increment of
> retryCount), the retryCount would be cleared at step #4.
> Since the intention of saslTimeoutSeen is to undo the increment due to
> retrying SaslTimeoutException, we should keep a counter for
> SaslTimeoutException retries and subtract the value of this counter from
> retryCount.
