推荐答案
您的confi有一些问题g文件：core-site.xml，hdfs-site.xml和mapred-site.xml。根据错误消息：
There is some problem with your config files: core-site.xml, hdfs-site.xml and mapred-site.xml. As per the error message:
java.lang.IllegalArgumentException：不包含有效主机：端口
权限：本地
java.lang.IllegalArgumentException: Does not contain a valid host:port authority: local
请查找正确的值，如果xml有效（小错字可能会破坏它）。
试试这些： hadoop作业跟踪器无法启动和启动hadoop Job Tracker时出错
Do look for correct values and if the xml is valid (a small typo can ruin it). Try these : hadoop job tracker cannot start up and Error in starting hadoop Job Tracker
