Sreekanth Ramakrishnan updated HADOOP-4930:
-------------------------------------------
Attachment: HADOOP-4930-12.patch
Attaching latest patch incorporating following offline comments from Hemanth:
* Changes made to build task-controller, now if no hadoop.conf.dir is passed to
build, then binary derives the path of the hadoop.conf.dir. The path which
binary is present is assumed to be $HADOOP_HOME/bin/task-controller and conf
directory is assumed to be $HADOOP_HOME/conf. If custom conf directory has to
be used, the same can be done by passing -Dhadoop.conf.dir=<directory> as
option while building task-controller.
* Cleaning up of malloced variables in configuration.c task-controller.c
output from ant test-patch is :

> 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.
