public interface PredictionSkylineStore

PredictionSkylineStore stores the predicted RLESparseResourceAllocation of a job as computed by the Estimator based on the ResourceSkylines of past executions in the HistorySkylineStore.

Method Summary

Modifier and Type	Method	Description
void	addEstimation(java.lang.String pipelineId, org.apache.hadoop.yarn.server.resourcemanager.reservation.RLESparseResourceAllocation resourceOverTime)	Add job's predicted Resource allocation to the store indexed by the pipelineId.
org.apache.hadoop.yarn.server.resourcemanager.reservation.RLESparseResourceAllocation	getEstimation(java.lang.String pipelineId)	Return the predicted Resource allocation for the pipeline.

Method Detail

addEstimation

void addEstimation(java.lang.String pipelineId,
                   org.apache.hadoop.yarn.server.resourcemanager.reservation.RLESparseResourceAllocation resourceOverTime)
            throws SkylineStoreException

Add job's predicted Resource allocation to the store indexed by the pipelineId.

Note that right now we only keep the latest copy of predicted Resource allocation for the recurring pipeline.

Parameters:

pipelineId - the id of the recurring pipeline.

resourceOverTime - the predicted Resource allocation for the pipeline.

Throws:

SkylineStoreException - if input parameters are invalid.

getEstimation

org.apache.hadoop.yarn.server.resourcemanager.reservation.RLESparseResourceAllocation getEstimation(java.lang.String pipelineId)
                                                                                             throws SkylineStoreException

Return the predicted Resource allocation for the pipeline.

If the pipelineId does not exist, it will return null.

Parameters:

pipelineId - the unique id of the pipeline.

Returns:

the predicted Resource allocation for the pipeline.

Throws:

SkylineStoreException - if pipelineId is null.
