Observe-secretly opened a new issue #9485: What does "/ tmp / hadoop-XXX / mapred / local" put here? It contains millions of small directories. This almost exhausted my "inode" resources. What does it store? How do I clean it up?

   Please provide a detailed title (e.g. "Broker crashes when using TopN query with Bound filter" instead of just "Broker crashes").
   
   ### Affected Version
   
   0.17.0
   
   ### Description
   
   We have a database. Submit a batch of data every minute. It saves 15 days. I think it should be caused by too many small files. But I don't know why it caused the problem described in the title. Please help me !!!
