When the wegiht component is executed through the proxy user mode, it will appear that the user does not have permission to read the file. After testing, it is found that the API is called incorrectly when obtaining the result set in the code. By default, the called API uses the permission of the user to which the JVM belongs to read HDFS
The content of this repair is to add specific user names and specify corresponding user permissions to read files
