   When I download a file from DS, if another program happens to upload the file to DS at this time, there will be a problem, even if the probability of the problem is relatively low. Taking HDFS as an example: If a program is reading a file from HDFS and another program uploads and replaces the file to HDFS, a problem will occur. I have added a testing method on #13480  to reproduce this issue。
   
   BTW，his issue has always existed, so does 3.1. x. Do both 3.1. x and dev need to raise PR？
