Description

In this document, http://hadoop.apache.org/docs/r2.7.0/hadoop-mapreduce-client/hadoop-mapreduce-client-core/mapred-default.xml, we can find the parameter "yarn.app.mapreduce.am.command-opts" is described as @taskid@ in yarn.app.mapreduce.am.command-opts can be replaced by current taskid. But I checked the code in 2.7.0, there is no logic to replace it.
