Botong Huang edited comment on YARN-6511 at 6/5/17 6:55 PM: ------------------------------------------------------------ Hi [~jianhe], thanks for the review! We only register UAM for the first time a sub-cluster is asked for. Please see _this.uamPool.hasUAMId(subClusterId.getId())_ in *registerWithNewSubClusters*. We will handle failed-to-register sub-clusters in the next iteration, where we will likely retry and consult the policy to fallback. I will fix the other minor issue in the next version.
