示例1: determineNrOfStepCopies
import org.pentaho.di.cluster.SlaveServer; //导入方法依赖的package包/类
/**
* Calculate the number of step copies in a step.<br>
* If a step is not running clustered, it's simply returning getCopies().<br>
* If a step is clustered and not doing any partitioning, it's simply returning getCopies().<br>
* If a step is clustered and partitioned, we need to look in the partitioning map for the specified slave server.<br>
* That is because the number of copies can vary over the slaves. (5 partitions over 3 slaves for example)
*
* @param slaveServer the slave server
* @param referenceStep the reference step
* @return the number of step copies that we run.
