Method Detail

getJobVertexStats

public Optional<VertexThreadInfoStats> getJobVertexStats(JobID jobId,
                                                         AccessExecutionJobVertex vertex)

Description copied from interface: VertexStatsTracker

Returns statistics for a job vertex. Automatically triggers sampling request if statistics are not available or outdated.

Specified by:

getJobVertexStats in interface VertexStatsTracker<VertexThreadInfoStats>

Parameters:

jobId - job the vertex belongs to

vertex - Vertex to get the stats for.

Returns:

Statistics for a job vertex. This interface is intended to be used for polling request and for the duration while the statistics are being gathered, the returned Optional can be empty.

getExecutionVertexStats

public Optional<VertexThreadInfoStats> getExecutionVertexStats(JobID jobId,
                                                               AccessExecutionJobVertex vertex,
                                                               int subtaskIndex)

Description copied from interface: VertexStatsTracker

Returns statistics for a execution vertex. Automatically triggers sampling request if statistics are not available or outdated.

Note: A single subtask may have multiple attempts, it will return the result of all attempts.

Specified by:

getExecutionVertexStats in interface VertexStatsTracker<VertexThreadInfoStats>

Parameters:

jobId - job the vertex belongs to

vertex - Vertex to get the stats for.

subtaskIndex - SubtaskIndex to get the stats for.

Returns:

Statistics for a execution vertex. This interface is intended to be used for polling request and for the duration while the statistics are being gathered, the returned Optional can be empty.

shutDown

public void shutDown()

Description copied from interface: VertexStatsTracker

Shuts the VertexStatsTracker down.

Specified by:

shutDown in interface VertexStatsTracker<VertexThreadInfoStats>
