Tsuyoshi OZAWA commented on YARN-1325: -------------------------------------- [~xgong], thank you for taking this JIRA. Your idea sounds good to me. It can help to avoid wrong operations. > Enabling HA should check Configuration contains multiple RMs > ------------------------------------------------------------ > > Key: YARN-1325 > URL: https://issues.apache.org/jira/browse/YARN-1325 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Tsuyoshi OZAWA > Assignee: Xuan Gong > Labels: ha > > 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). -- This message was sent by Atlassian JIRA (v6.1#6144)
