hadoop配置错误总结

2016-06-02 17:33:04,163 ERROR org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: RECEIVED SIGNAL 15: SIGTERM
2016-06-02 17:33:04,173 ERROR org.apache.hadoop.security.token.delegation.AbstractDelegationTokenSecretManager: ExpiredTokenRemover received java.lang.InterruptedException: sleep interrupted

可能原因：ResourceManager无法管理下面的datamanager 无法获取datanode的资源信息
我的误是 对master做了二次域名遇刺
127.0.0.1 master
192.168.100.80 master
hadoop 中使用master 别名时，域名解析只能识别127.0.0.1 IP
远程主机无法访问192.168.100.80
所以出现上述错误
