Robert Metzger commented on FLINK-18899:
----------------------------------------

[~fly_in_gis] What do you think about this ticket? Does it make sense to extend the description of "yarn.application-attempts" and explain the overwritten values in HA mode?

>          Issue Type: Bug
>          Components: Deployment / YARN, Documentation

> The document [https://ci.apache.org/projects/flink/flink-docs-release-1.11/ops/config.html#yarn-application-attempts] shows the yarn.application-attempts default value is none, but I found codes in  org.apache.flink.yarn.YarnClusterDescriptor class like below:
> {code:java}
> if (HighAvailabilityMode.isHighAvailabilityModeActivated(configuration)) {
>    // activate re-execution of failed applications
>    appContext.setMaxAppAttempts(
>          configuration.getInteger(
>                YarnConfigOptions.APPLICATION_ATTEMPTS.key(),
>                YarnConfiguration.DEFAULT_RM_AM_MAX_ATTEMPTS));
>    activateHighAvailabilitySupport(appContext);
> } else {
>    // set number of application retries to 1 in the default case
>    appContext.setMaxAppAttempts(
>          configuration.getInteger(
>                YarnConfigOptions.APPLICATION_ATTEMPTS.key(),
>                1));
> }
> {code}
> This means, if HA mode, the default value is from Yarn(default 2), otherwise the default value is 1.
