Sreekanth Ramakrishnan updated HADOOP-4930:
-------------------------------------------
Attachment: HADOOP-4930-3.patch
Attaching latest patch:
Change log:
* Changed autoconf script in following way:
** --with-confdir has to be passed when running configure. The value of the
argument should be the HADOOP_CONF_DIR where the binary would be deployed.
** --prefix is used to denote the location where the binary should be
installed, the default prefix has been changed to the current directory,
(probably wrong idea, but this was done not to pollute the binary path in the
machine where make install is run)
** config.h has been removed and task-controller.h is the header file which is
now generated by configure
* task-controller.c: now uses fgets to read from configuration file, instead of
complicated fgetc.
> Implement setuid executable for Linux to assist in launching tasks as job
> owners

> 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.
