> Change default of yarn.application-attempt-failures-validity-interval to -1
> ---------------------------------------------------------------------------
>
> Key: FLINK-38112
> URL: https://issues.apache.org/jira/browse/FLINK-38112
> Project: Flink
> Issue Type: Improvement
> Components: Deployment / YARN
> Reporter: yude
> Priority: Minor
> Labels: configuration, default, pull-request-available, yarn
>
> This pull request aligns Flink’s default for the YARN configuration option
> {{yarn.application-attempt-failures-validity-interval}} with YARN itself.
> The previous default (10 000 ms) caused unexpected endless AM restarts once
> the interval between two failures exceeded ten seconds.
> *Why {{-1}} instead of another fixed window?*
> Since every environment performs differently, some restart AM in 30 seconds,
> some in 3 seconds. There is no fixed time that fits everyone.
> Setting the default to *{{-1}} (global counting)* removes the hidden
> assumption and lets users choose a window that matches their own
> infrastructure when needed.
