jiangxb1987 commented on issue #27943: [SPARK-31179] Fast fail the connection while last connection failed in the last retry IO wait URL: https://github.com/apache/spark/pull/27943#issuecomment-602941555 Agree the fail fast time window length should be a little less than `conf.ioRetryWaitTimeMs()` so you will not fail the retried connection immediately. Also I'm curious could this lead to the scenario that, when you have two tasks and only one client, the connection request from the second task may fail fast every time it tries to connect (because the connection from the first task always fail beforehand)?
