------------------------------------

Hi Eugene,

The patch's additions look good, but the location is wrong. We can rather add it to ./hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/resources/mapred-default.xml itself, as thats the real place thats to be used (even job history server uses the MR core).

I will update your patch to add it in here and commit it in after that. Thank you!
