zhihai xu created YARN-3106:
-------------------------------

             Summary: The message in IllegalArgumentException gave wrong information in NMTokenSecretManagerInRM.java
and RMContainerTokenSecretManager.java
                 Key: YARN-3106
                 URL: https://issues.apache.org/jira/browse/YARN-3106
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
            Reporter: zhihai xu
            Assignee: zhihai xu
            Priority: Minor


The message in IllegalArgumentException gave wrong information in NMTokenSecretManagerInRM.java
and RMContainerTokenSecretManager.java.
We saw this error message:
{code}
Error starting ResourceManager
java.lang.IllegalArgumentException: yarn.resourcemanager.nm-tokens.master-key-rolling-interval-secs
should be more than 2 X yarn.nm.liveness-monitor.expiry-interval-ms
{code}
After I checked the source code, I find this error message misleading.
The following is code from NMTokenSecretManagerInRM.java
{code}
    rollingInterval = this.conf.getLong(        YarnConfiguration.RM_NMTOKEN_MASTER_KEY_ROLLING_INTERVAL_SECS,
   YarnConfiguration.DEFAULT_RM_NMTOKEN_MASTER_KEY_ROLLING_INTERVAL_SECS)  * 1000;
    this.activationDelay =        (long) (conf.getLong(YarnConfiguration.RM_NM_EXPIRY_INTERVAL_MS,
            YarnConfiguration.DEFAULT_RM_NM_EXPIRY_INTERVAL_MS) * 1.5);
    LOG.info("NMTokenKeyRollingInterval: " + this.rollingInterval
        + "ms and NMTokenKeyActivationDelay: " + this.activationDelay
        + "ms");
    if (rollingInterval <= activationDelay * 2) {
      throw new IllegalArgumentException(         YarnConfiguration.RM_NMTOKEN_MASTER_KEY_ROLLING_INTERVAL_SECS
             + " should be more than 2 X "
              + YarnConfiguration.RM_NM_EXPIRY_INTERVAL_MS);
    }
{code}
It should be 3 X not 2 X.
Same error also happened in RMContainerTokenSecretManager.java.
{code}
   this.rollingInterval = conf.getLong(   YarnConfiguration.RM_CONTAINER_TOKEN_MASTER_KEY_ROLLING_INTERVAL_SECS,
      YarnConfiguration.DEFAULT_RM_CONTAINER_TOKEN_MASTER_KEY_ROLLING_INTERVAL_SECS) * 1000;
    this.activationDelay =
        (long) (conf.getLong(YarnConfiguration.RM_NM_EXPIRY_INTERVAL_MS,
            YarnConfiguration.DEFAULT_RM_NM_EXPIRY_INTERVAL_MS) * 1.5);
    LOG.info("ContainerTokenKeyRollingInterval: " + this.rollingInterval
        + "ms and ContainerTokenKeyActivationDelay: " + this.activationDelay
        + "ms");
    if (rollingInterval <= activationDelay * 2) {
      throw new IllegalArgumentException(      YarnConfiguration.RM_CONTAINER_TOKEN_MASTER_KEY_ROLLING_INTERVAL_SECS
             + " should be more than 2 X "            +YarnConfiguration.RM_CONTAINER_TOKEN_MASTER_KEY_ROLLING_INTERVAL_SECS);
    }
{code}
