Subject [jira] [Created] (YARN-1325) RMHAProtocolService#serviceInit should check configuration contains multiple RM
Date Fri, 18 Oct 2013 23:35:41 GMT
Tsuyoshi OZAWA created YARN-1325:
------------------------------------

             Summary: RMHAProtocolService#serviceInit should check configuration contains
multiple RM
                 Key: YARN-1325
                 URL: https://issues.apache.org/jira/browse/YARN-1325
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
            Reporter: Tsuyoshi OZAWA


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).
