[jira] Updated: (HADOOP-3729) Integrate TaskTracker with the Service base class

Posted by "Steve Loughran (JIRA)" <ji...@apache.org>.

Steve Loughran updated HADOOP-3729:
-----------------------------------

    Attachment: hadoop-3729.patch

tasktracker changes. I'm not convinced this is stable, but I'm going offline for two weeks, and wanted to leave this to say "here is what to work with"

* The constructor is a bit convoluted, as unlike the other Services, a static factory method is not used to create the class. The existing TaskTracker(JobConf) initialises and starts the component by default, but subclasses have the option of disabling this, which they should do.

* Cleanup threads get shut down too (HADOOP-3727) . Termination is seemingly stable when the service is not fully started, though tests are needed for that. 

* the tracker can be closed/initialized repeatedly
