Method Detail

startWebRuntimeMonitor

public static WebMonitor startWebRuntimeMonitor(org.apache.flink.configuration.Configuration config,
                                                LeaderRetrievalService leaderRetrievalService,
                                                akka.actor.ActorSystem actorSystem)

Starts the web runtime monitor. Because the actual implementation of the runtime monitor is in another project, we load the runtime monitor dynamically.

Because failure to start the web runtime monitor is not considered fatal, this method does not throw any exceptions, but only logs them.

Parameters:

config - The configuration for the runtime monitor.

leaderRetrievalService - Leader retrieval service to get the leading JobManager

fromKeyValueJsonArray

public static Map<String,String> fromKeyValueJsonArray(String jsonString)

createDetailsForJob

public static JobDetails createDetailsForJob(ExecutionGraph job)
