tison,你好运行到这里时,报空指针
Caused by: java.lang.NullPointerException
    at 
org.apache.hadoop.yarn.client.api.impl.YarnClientImpl.getNodeReports(YarnClientImpl.java:506)

getNodeReports方法中:
GetClusterNodesResponse response = rmClient.getClusterNodes(request);
这句的rmClient为null值。



我看YarnClientImpl中,有个start()可为rmClient赋值,但是,我加上此方法执行时又会报以下错误:
Exception in thread "main" org.apache.hadoop.service.ServiceStateException: 
org.apache.hadoop.yarn.client.api.impl.YarnClientImpl cannot enter state 
STARTED from state NOTINITED
