   Hello, there is still a problem under the modified logic:
   If you copy a resource file and there is FileNotFoundException (the file is 
in the resource list, but not in HDFS), you will still not see the relevant 
error message in the task log of the Web UI, making it difficult to 
troubleshoot the problem

   您好,在现在修改后的逻辑下,还存在一个问题是:
   如果在copy资源文件时发生文件不存在异常(文件在资源列表中,但是在hdfs上不存在的特殊情况下),那么在web 
UI的task日志中还是看不到相关错误信息,不便于排查问题
