[jira] [Created] (HAWQ-715) hawq_rm_yarn_address doesn't take effect if libyarn is in HA mode

Lin Wen created HAWQ-715:
----------------------------

             Summary: hawq_rm_yarn_address doesn't take effect if libyarn is in HA mode
                 Key: HAWQ-715
                 URL: https://issues.apache.org/jira/browse/HAWQ-715
             Project: Apache HAWQ
          Issue Type: Bug
          Components: libyarn
            Reporter: Lin Wen
            Assignee: Lei Chang


Currently if libyarn is in HA mode, hawq_rm_yarn_address/hawq_rm_yarn_scheduler_address doesn't take effect but still need users configure them in haw-site.xml, hawq will iteratively use the hosts listed in property  yarn.resourcemanager.ha/yarn.resourcemanager.scheudler.ha in yarn-client.xml, until hawq finds out an active YARN Resource Manager.

A better way is,
hawq_rm_yarn_address/hawq_rm_yarn_scheduler_address in hawq-site.xml are required to be configured in HA mode, and will be considered as active RM to connect firstly, if failed, then HAWQ will connect the other hosts listed in yarn.resourcemanager.ha/yarn.resourcemanager.scheudler.ha
