Subject [jira] Updated: (HADOOP-4930) Implement setuid executable for Linux to assist in launching tasks as job owners
Date Fri, 06 Feb 2009 06:13:59 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4930?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Sreekanth Ramakrishnan updated HADOOP-4930:

    Attachment: HADOOP-4930-10.patch

Attaching latest patch with Giri's offline comments:

* Added autoreconf target which all c++ projects use in create-c++-configure target.
* Made autoconf version check to 2.59
* Removed a superfluous target called checkproperty, as currently HADOOP_CONF_DIR is taken
as "../conf" when task-controller is built, i.e. binary would be built with a relative path
to task-controller.cfg. If users require to change it to absolute path can pass it on as -Dhadoop.conf.dir

> HADOOP-4490 tracks the design and implementation of launching tasks as job owners. As
per discussion there, the proposal is to implement a setuid executable for Linux that would
be launched by the tasktracker to run tasks as the job owners. In this task we will track
the implementation of the setuid executable. HADOOP-4490 will be used to track changes in
the tasktracker.
