   > Some more thoughts/question:
   > 
   > 1. Why are two configs in Hive for this?
   > 
   > * mapred.input.dir.recursive
   > * hive.mapred.supports.subdirectories
   > 
   > 1. How does Hive do when only one is true? If there both needed we need to 
check both too!
   > 2. Please update the title: skip the part "when configuration is enable" 
and reword the rest.
   >    What about "Supporting non-partitioned Hive tables with subdirectories".
   > 3. Please update the description, too. In "What changes were proposed in 
this pull request?" its enough if you explain the the title a bit more. I 
suggest to use a spell checker to avoid errors like: setted => set, 
configurtions => configuration.
   >    Please note the PR description is extremely important as after the PR 
is merged it will be the commit message.
   > 4. At "Does this PR introduce any user-facing change?" elaborate on the 
impact of this change. Remove the "maybe we could add this option in documents 
to notice users for the enhancement." which I think is a good idea and should 
be part of this PR.
   
   got it, it's a great help for me, really appreciated! 
   I'll address all the questions you mentioned.
