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無法管理下面的datamanager 無法獲取datanode的資源信息
我的誤是 對master做了二次域名遇刺
127.0.0.1 master
192.168.100.80 master
hadoop 中使用master 別名時，域名解析只能識別127.0.0.1 IP
遠程主機無法訪問192.168.100.80
所以出現上述錯誤
