 Review comment:
   this is mostly used by tests, right?  I think we should just replace those 
with Junit temporary folder or use `Files.createTempDirectory()` from jdk here 
instead of creating it by hand.. This code and the retry loops can be 
simplified to 1 line, java will set up hooks to delete the directories on exit 
etc, if we do that..

 Review comment:
   this probably can be just replaced by a concrete map impl in place right? 
this sort of usage does not really warrant the builder pattern IMO.

 Review comment:
   I am wondering if we can eliminate the need for this class and the builder 
class, but replacing with plain hashmaps inline? 
   - in places where a static HashMap is needed we can use the map 
initialization syntax I pasted above. 
   
   Don't feel very strongly about this,, but thinking if we can avoid builder 
patterns where it actually is not used that way.
