Method Detail

getID

TezDAGID getID()

getLocalResources

Map<String,org.apache.hadoop.yarn.api.records.LocalResource> getLocalResources()

getName

String getName()

Specified by:

getName in interface DagInfo

getState

getReport

DAGReport getReport()

getAllCounters

Get all the counters of this DAG. This includes job-counters aggregated together with the counters of each task. This creates a clone of the Counters, so use this judiciously.

Returns:

job-counters and aggregate task-counters

getCachedCounters

getVertex

Vertex getVertex(String vertexName)

Get Vertex by vertex name

getVertices

Map<TezVertexID,Vertex> getVertices()

getVertex

Vertex getVertex(TezVertexID vertexId)

getDiagnostics

List<String> getDiagnostics()

getSuccessfulVertices

int getSuccessfulVertices()

getProgress

float getProgress()

getCompletedTaskProgress

float getCompletedTaskProgress()

isUber

boolean isUber()

getUserName

String getUserName()

getDAGStatus

DAGStatusBuilder getDAGStatus(Set<StatusGetOpts> statusOptions,
                              long timeout)
                       throws TezException

Throws:

TezException

getVertexStatus

getDAGScheduler

@Nullable
DAGScheduler getDAGScheduler()

Returns:

the DAGScheduler that will schedule this DAG, null if it doesn't exist
