Subject Removal of unused properties
Date Thu, 09 Apr 2015 11:33:40 GMT
Hi Folks,

In MAPREDUCE-6307, I'd like to remove unused 
"mapreduce.tasktracker.taskmemorymanager.monitoringinterval" property, 
however, the compatibility document says "Hadoop-defined properties are 
to be deprecated at least for one major release before being removed."

http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-common/Compatibility.html#Hadoop_Configuration_Files

Is it applicable for unused properties?
Can we remove unused properties right now?

Regards,
Akira
