Hudson commented on YARN-1325:
------------------------------

FAILURE: Integrated in Hadoop-Yarn-trunk #420 (See [https://builds.apache.org/job/Hadoop-Yarn-trunk/420/])
YARN-1325. Modified RM HA configuration validation to also ensure that multiple RMs are configured.

> Currently, we can enable RM HA configuration without multiple RM ids(YarnConfiguration.RM_HA_IDS).
 This behaviour can cause wrong operations. ResourceManager should verify that more than 1
RM id must be specified in RM-HA-IDs.
> One idea is to support "strict mode" to enforce this check as configuration(e.g. yarn.resourcemanager.ha.strict-mode.enabled).
