在示例目录中运行KMeans.jar时，出现了一些错误，并且版本为flink-0.10.1-bin-hadop1-scala_2.10我运行的env是cygwin64，错误如下：
root@HIH-D /cygdrive/d/Development/flink-0.10.1-bin-hadoop1-scala_2.10/flink-0.10.1/kmeans
运行
# java -cp ../examples/KMeans.jar:../lib/flink-dist-0.10.1.jar org.apache.flink.examples.java.clustering.util.KMeansDataGenerator -points 500 -k 10 -stddev 0.08 -output `pwd`
给出
ClassNotFoundException: org.apache.flink.examples.java.clustering.util.KMeansDataGenerator
我只是在本地尝试了一下，结果成功了。我认为classpath（-cp）参数设置不正确。
你能试着从你正在调用KMeansDataGenerator的目录中执行jar tf ../examples/KMeans.jar吗？（在：D /cygdrive/d/Development/flink-0.10.1-bin-hadoop1-scala_2.10/flink-0.10.1/kmeans中）。
