   With respect to the partial files, when the feature flag is enabled, it will 
reduce the possibility of a partial data files getting created.  Since second 
and subsequent attempts, in the presence of of completed marker, would return 
success (with previously completed writeStatus) we are minimizing multiple 
tasks attempting to create files.
   
   Deleting the .hoodie/.temp/<ts>  marker folder, after the finalizeWrite, 
ensures that any new task attempting to create a data file (that would show up 
as a partially written file, when the Job/JVM exits) will fail at the time of 
writeHandle creation, if the marker folder is absent (and not create a partial 
file).
