Subject [jira] Updated: (HADOOP-3729) Integrate TaskTracker with the Service base class
Date Wed, 09 Jul 2008 16:59:31 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3729?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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
