Peng created FLINK-18899:
----------------------------
Summary: The property yarn.application-attempts default value is
not none
Key: FLINK-18899
URL: https://issues.apache.org/jira/browse/FLINK-18899
Project: Flink
Issue Type: Bug
Components: Documentation
Affects Versions: 1.11.0
Reporter: Peng
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.
