Subject [jira] [Updated] (MAPREDUCE-6379) @taskid@ in yarn.app.mapreduce.am.command-opts can't be replaced by current taskid
Date Mon, 04 Jan 2016 23:29:39 GMT

Ray Chiang updated MAPREDUCE-6379:
----------------------------------
    Attachment: MAPREDUCE-6379.001.patch

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.
