我得到一个：
每次我尝试上传文件时，HUE中的Error: Undefined message。我可以在HDFS中创建一个子目录/文件夹，但文件上传不起作用。
我尝试使用hadoop用户从linux CLI将一个文件复制到HDFS，结果成功了。
色调用户为hadoop
HDFS目录所有者是hadoop:hadoop
编辑：添加错误

正如您从错误消息中看到的，它报告在hue尝试执行CHECKACCESS操作时传递的查询参数没有找到匹配项。
http://IRedactedMyinstanceIdentHere.ap-southeast-1.compute.internal:14000/webhdfs/v1/user/hadoop/Test-Data?op=CHECKACCESS&fsaction=rw-&user.name=hue&doas=hadoop
{"RemoteException":{"message":"java.lang.IllegalArgumentException: No enum constant org.apache.hadoop.fs.http.client.HttpFSFileSystem.Operation.CHECKACCESS","exception":"QueryParamException","javaClassName":"com.sun.jersey.api.ParamException$QueryParamException"}}
这个实现在一些hadoop版本中似乎丢失了，并且是HTTPFS-CHECKACCESS操作丢失的已知错误。
