我在运行mapreduce工作时遇到错误。
Failed on local exception:
com.google.protobuf.InvalidProtocolBufferException:Protocol message end-group tag did not match expected tag.;
Host Details : local host is: "hadoop0/10.2.4.9"; destination host is: "0.0.0.0":10020;
我的/ etc / hosts配置正确，所有配置文件，如hdfs-site.xml，yarn-site.xml，core-site.xml和mapred-site.xml应该没问题，因为我用过这个之前的另一个集群中的代码
HDFS很好，我可以把文件放到HDFS。
你知道什么是错的吗？
以下是错误堆栈：
