morningman opened a new pull request, #21276:
URL: https://github.com/apache/doris/pull/21276

   …ache in memory
   
   ## Proposed changes
   
   FileInputFormat.setInputPaths() will call FileSystem.get(), which will 
create new FileSystem
   and save it in FileSystem.Cache. We don't need this cache.
   And if user call `refresh catalog` frequently, there will be lots of fs 
cache in it, causing OOM
   
   ## Further comments
   
   If this is a relatively large or complex change, kick off the discussion at 
[d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you 
chose the solution you did and what alternatives you considered, etc...
