Bibin A Chundatt commented on YARN-4087:
----------------------------------------

So by  default in yarn-default.xml 

yarn.resourcemanager.fail-fast=true
yarn.fail-fast=false

In YarnConfiguration

{code}
  public static boolean shouldRMFailFast(Configuration conf) {
    return conf.getBoolean(YarnConfiguration.RM_FAIL_FAST,
        conf.getBoolean(YarnConfiguration.YARN_FAIL_FAST,
            YarnConfiguration.DEFAULT_YARN_FAIL_FAST));
  }
{code}

some mismatch rt?

No plans to change YarnConfiguration.RM_FAIL_FAST.

> Increasingly, I feel setting this property to be false makes more sense
