[jira] [Updated] (MAPREDUCE-6379) @taskid@ in
yarn.app.mapreduce.am.command-opts can't be replaced by current taskid

Putting in a file to jumpstart the conversation. The AM doesn't have a "task ID" per-se. Is the Application ID what was intended?

> 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.
