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 hadoop-0.20.205 和 hbase-0.90.4 等 hbase 旧版本中工作，它不适用于 hadoop-1.0.3 和 hbase-0.94.1 等早期版本。
错误详情 ：
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)
