[jira] Commented: (MAPREDUCE-1753) Implement a functionality for suspend and resume a task's process.
[ https://issues.apache.org/jira/browse/MAPREDUCE-1753?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=12869363#action_12869363 ] Konstantin Boudnik commented on MAPREDUCE-1753: --- It isn't about my satisfaction. It's two bits return value which is done as boolean type. C language doesn't have it that's why they use integer instead. Now, about suspend resume process: you are right, it is generic. Which technically allow to suspend a daemon VM's process and never be able to resume it. But It seems to be Ok, I guess. I was totally confused by the fact that this has been tracked by a MAPREDUCE JIRA :( I'm moving this ticket out to HADOOP.

Actually I am not suspending the daemonprocess. I am just suspending the task attempt process id that is running on I have edited the name of the JIRA. Please update the JavaDocs accordingly. It should clear state that the suspend is done for a task's process.

You can suspend or resume any process if you know the process id. It's not specific to only task processes. So that I have given the description in more generic way instead of mentioning task process. If you see, these two methods are implemented in DaemonProtocolAspect.aj file for utilizing the other purposes.Otherwise if it is task level, we can implement in TaskTrackerAspect.aj itself.
