> 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
