- - ### Method Detail

    - #### prepare

          void prepare​(Map<String,​Object> topoConf,
                       String schedulerLocalDir)

    - #### getSupervisorId

          String getSupervisorId()

      The id used for writing metadata into ZK.

    - #### getAssignmentId

          String getAssignmentId()

      The id used in assignments. This combined with confirmAssigned decides what this supervisor is responsible for. The combination of this and getSupervisorId allows Nimbus to assign to a single machine and have multiple supervisors on that machine execute the assignment. This is important for achieving resource isolation.

    - #### getMetadata

          Object getMetadata()

    - #### confirmAssigned

          boolean confirmAssigned​(int port)

    - #### killedWorker

          void killedWorker​(int port)

    - #### assigned

          void assigned​(Collection<Integer> ports)
