Eric Yang commented on YARN-7129:
---------------------------------

[~jeagles] {quote}I may have missed it, but I don't feel this comment was 
addressed. Are we still bundling multiple features into this jira? What I see 
is that there is still a 1MB+ patch and looks like we are trying to commit to a 
top level umbrella jira.{quote}

Most of the patch is in fonts directory and a class that generates random 
English sound alike words.  The actual code is small when those pieces are 
removed. 
 The rest of the code basically setup maven project framework for each of the 
necessary pieces to go into sub modules.  Patch size is not a good metric to 
review New Feature patches.  There are many examples of New Feature issues with 
big patch, e.g. YARN-913, YARN-2928, HADOOP-8562 and many others.  
[~billie.rinaldi] has done the due-diligence in reviewing the patch with detail 
step by step improvements and had committed when basic structure is working.

The people who are interested in the application catalog have already done the 
reviews and acquired the knowledge of inner work of this patch.  Breaking down 
the patch further at this point in time, would not help the community other 
than introducing additional logistic overhead to check for correctness that had 
already been checked.  People have already been involved and able to reproduce. 
 Clear javadoc and documentation are also included for a good starting 
trajectory.  

If you think otherwise, please list details of how you want the refactoring 
done.  I will comply and request your reviews.
