zhuzhurk opened a new pull request, #20221:
URL: https://github.com/apache/flink/pull/20221
## What is the purpose of the change
Previously, FailureHandlingResultSnapshot was always created to treat the
only current attempt of an execution vertex as the failed execution. This is no
longer right in speculative execution cases, in which an execution vertex can
have multiple current executions, and any of them may fail.
