Example 1 with NimbusSummary

use of backtype.storm.generated.NimbusSummary in project jstorm by alibaba.

the class NimbusUtils method getNimbusSummary.

public static NimbusSummary getNimbusSummary(StormClusterState stormClusterState, List<SupervisorSummary> supervisorSummaries, NimbusData data) throws Exception {
    NimbusSummary ret = new NimbusSummary();
    String master = stormClusterState.get_leader_host();
