我正在尝试在HBase中进行批量加载，但加载数据时会出现以下异常...
应用程序application_1439213972129_0080初始化失败(exitCode = 255)，输出如下:请求的用户root未列入白名单，且id为0，该值低于允许的最小值500
尝试失败。应用程序失败。

最佳答案
看起来您是在不在hbase中的MapR DB中加载数据，但是其优良的hbase命令与MarDB兼容。我只是在您的命令中做了一个小改动，看看是否对您有用。
hbase org.apache.hadoop.hbase.mapreduce.ImportTsv -Dimporttsv.columns = HBASE_ROW_KEY，个人:名称，专业:职位名称，专业:部门:个人，员工:年度工资'-Dimporttsv.separator = _al / maps / tables / /apps/Datasets/Employee_Details.csv
