Method Detail

getID

org.apache.tez.dag.records.TezDAGID getID()

getLocalResources

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

getName

String getName()

getState

DAGState getState()

getReport

DAGReport getReport()

getAllCounters

org.apache.tez.common.counters.TezCounters 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

getVertex

Vertex getVertex(String vertexName)

Get Vertex by vertex name

getVertices

Map<org.apache.tez.dag.records.TezVertexID,Vertex> getVertices()

getVertex

Vertex getVertex(org.apache.tez.dag.records.TezVertexID vertexId)

getDiagnostics

List<String> getDiagnostics()

getTotalVertices

int getTotalVertices()

getSuccessfulVertices

int getSuccessfulVertices()

getProgress

float getProgress()

isUber

boolean isUber()

getUserName

String getUserName()

getConf

org.apache.hadoop.conf.Configuration getConf()

getJobPlan

org.apache.tez.dag.api.records.DAGProtos.DAGPlan getJobPlan()

getDAGStatus

DAGStatusBuilder getDAGStatus(Set<org.apache.tez.dag.api.client.StatusGetOpts> statusOptions)

getVertexStatus

VertexStatusBuilder getVertexStatus(String vertexName,
                                  Set<org.apache.tez.dag.api.client.StatusGetOpts> statusOptions)

isComplete
