• ArchivedExecutionVertex adds method to return prior executions.
• get prior execution attempt

AccessExecution execution = executionVertex.getCurrentExecutionAttempt();

int currentAttemptNum = execution.getAttemptNumber();

JobID jobID = request.getPathParameter(JobIDPathParameter.class);

JobVertexID jobVertexID = request.getPathParameter(JobVertexIdPathParameter.class);

List<SubtaskExecutionAttemptDetailsInfo> allAttempts = new ArrayList<>();

allAttempts.add(SubtaskExecutionAttemptDetailsInfo.create(execution, metricFetcher, jobID, jobVertexID));

if (currentAttemptNum > 0) {

  for (int i = currentAttemptNum - 1; i >= 0; i--) {

    AccessExecution currentExecution = executionVertex.getPriorExecutionAttempt(i);

    if (currentExecution != null) {

      allAttempts.add(SubtaskExecutionAttemptDetailsInfo.create(currentExecution, metricFetcher, jobID, jobVertexID));

    }

  }

• by ArchivedExecutionVertex.getPriorExecutionAttempts()
• add SubtaskAllExecutionAttemptsDetailsHandler for failed attempt
