Ted Yu updated SPARK-42090:
---------------------------
Description:
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.
