Gunther Hagleitner commented on HIVE-3428:
------------------------------------------

Patch doesn't seem to provide configuration for hadoop.mr.rev=20S (hadoop 
1-line). More importantly, if the only difference between the files is the 
Hadoop's deprecated EventCounter, it seems better to create a shim class for 
that. This way there's only one conf file and hive will pick the right file 
from the classpath at runtime.
