Subject [jira] [Commented] (MAPREDUCE-6307) Deprecate mapreduce.tasktracker.taskmemorymanager.monitoringinterval

Akira AJISAKA commented on MAPREDUCE-6307:
------------------------------------------

I agree with you, however, the document (http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-common/Compatibility.html#Hadoop_Configuration_Files)
says

bq. Hadoop-defined properties are to be deprecated at least for one major release before being
removed. Modifying units for existing properties is not allowed.

My question is: The sentences are applicable for unused properties? I'd like to discuss this
issue in dev ML.

deprecate the property.
