在使用远程连接连接到hbase时，出现以下错误。注意：但是相同的代码在hbase较旧的版本（如hadoop-0.20.205和hbase-0.90.4）中工作，而在hadoop-1.0.3和hbase-0.94.1等早期版本中不工作。
错误详细信息：

WARN client.HConnectionManager: Error obtaining current user, skipping username in HConnectionKey
java.io.IOException: failure to login at
org.apache.hadoop.security.UserGroupInformation.getLoginUser(UserGroupInformation.java:490)
