Constructor Detail

JobExecutionResult

public JobExecutionResult(JobID jobID,
                  long netRuntime,
                  Map<String,Object> accumulators)

Creates a new JobExecutionResult.

Parameters:

jobID - The job's ID.

netRuntime - The net runtime of the job (excluding pre-flight phase like the optimizer) in milliseconds

accumulators - A map of all accumulators produced by the job.

Method Detail

getNetRuntime

public long getNetRuntime()

Gets the net execution time of the job, i.e., the execution time in the parallel system, without the pre-flight steps like the optimizer.

Returns:

The net execution time in milliseconds.

getNetRuntime

public long getNetRuntime(TimeUnit desiredUnit)

Gets the net execution time of the job, i.e., the execution time in the parallel system, without the pre-flight steps like the optimizer in a desired time unit.

Parameters:

desiredUnit - the unit of the NetRuntime

Returns:

The net execution time in the desired unit.

getAccumulatorResult

public <T> T getAccumulatorResult(String accumulatorName)

Gets the accumulator with the given name. Returns null, if no accumulator with that name was produced.

Type Parameters:

T - The generic type of the accumulator value.

Parameters:

accumulatorName - The name of the accumulator.

Returns:

The value of the accumulator with the given name.

getAllAccumulatorResults

public Map<String,Object> getAllAccumulatorResults()

Gets all accumulators produced by the job. The map contains the accumulators as mappings from the accumulator name to the accumulator value.

Returns:

A map containing all accumulators produced by the job.

getIntCounterResult

public Integer getIntCounterResult(String accumulatorName)

Gets the accumulator with the given name as an integer.

Parameters:

accumulatorName - Name of the counter

Returns:

Result of the counter, or null if the counter does not exist

Throws:

ClassCastException - Thrown, if the accumulator was not aggregating a Integer

fromJobSubmissionResult

public static JobExecutionResult fromJobSubmissionResult(JobSubmissionResult result)

Returns a dummy object for wrapping a JobSubmissionResult

Parameters:

result - The SubmissionResult

Returns:

a JobExecutionResult
