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)
