Method Detail

requestRestAddress

CompletableFuture<String> requestRestAddress(org.apache.flink.api.common.time.Time timeout)

Requests the REST address of this RpcEndpoint.

Parameters:

timeout - for this operation

Returns:

Future REST endpoint address

requestJob

CompletableFuture<AccessExecutionGraph> requestJob(org.apache.flink.api.common.JobID jobId,
                                                   org.apache.flink.api.common.time.Time timeout)

Requests the AccessExecutionGraph for the given jobId. If there is no such graph, then the future is completed with a FlinkJobNotFoundException.

Parameters:

jobId - identifying the job whose AccessExecutionGraph is requested

timeout - for the asynchronous operation

Returns:

Future containing the AccessExecutionGraph for the given jobId, otherwise FlinkJobNotFoundException

requestJobDetails

CompletableFuture<MultipleJobsDetails> requestJobDetails(boolean includeRunning,
                                                         boolean includeFinished,
                                                         org.apache.flink.api.common.time.Time timeout)

Requests job details currently being executed on the Flink cluster.

Parameters:

includeRunning - true if running jobs shall be included, otherwise false

includeFinished - true if finished jobs shall be included, otherwise false

timeout - for the asynchronous operation

Returns:

Future containing the job details

requestClusterOverview

CompletableFuture<ClusterOverview> requestClusterOverview(org.apache.flink.api.common.time.Time timeout)

Requests the cluster status overview.

Parameters:

timeout - for the asynchronous operation

Returns:

Future containing the status overview

requestMetricQueryServicePaths

CompletableFuture<Collection<String>> requestMetricQueryServicePaths(org.apache.flink.api.common.time.Time timeout)

Requests the paths for the MetricQueryService to query.

Parameters:

timeout - for the asynchronous operation

Returns:

Future containing the collection of metric query service paths to query

requestTaskManagerMetricQueryServicePaths

CompletableFuture<Collection<org.apache.flink.api.java.tuple.Tuple2<ResourceID,String>>> requestTaskManagerMetricQueryServicePaths(org.apache.flink.api.common.time.Time timeout)

Requests the paths for the TaskManager's MetricQueryService to query.

Parameters:

timeout - for the asynchronous operation

Returns:

Future containing the collection of instance ids and the corresponding metric query service path
