Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.6.0
Environment: some properties in yarn-site.xml：
<property>
<name>yarn.resourcemanager.recovery.enabled</name>

Reporter: tim yu
I am trying to make Flink (1.11.1) job on our Hadoop cluster (2.6.0) with HA
enabled but when I test it out by killing the active RM it brings down the
entire cluster.
I have configured Flink's HA in flink-conf.yml.
When I try to kill the active RM using kill -9, YARN correctly switches to the
standby RM and I can see applications as ACCEPTED for a minute but soon the
standby RM crashes throwing the following exception:

I found some code about submitting high-availability jobs in flink project:
private void activateHighAvailabilitySupport(ApplicationSubmissionContext
appContext) throws
InvocationTargetException, IllegalAccessException {
ApplicationSubmissionContextReflector reflector =
ApplicationSubmissionContextReflector.getInstance();
reflector.setKeepContainersAcrossApplicationAttempts(appContext, true);
reflector.setAttemptFailuresValidityInterval(
appContext,
flinkConfiguration.getLong(YarnConfigOptions.APPLICATION_ATTEMPT_FAILURE_VALIDITY_INTERVAL));
}
Flink HA jobs set KeepContainersAcrossApplicationAttempts to true.
