Hemanth Yamijala commented on MAPREDUCE-1418:
---------------------------------------------
The following functions in task-controller need modification:
- initialize_user
- initialize_task
- initialize_job
- initialize_distributed_cache_file
I will try and add unit tests in appropriate LinuxTaskController related test
classes that call the taskcontroller with relative paths in arguments and
verify the right error occurs.
> LinuxTaskController binary misses validation of arguments passed for relative
> components in some cases.

> The function {{int check_path_for_relative_components(char * path)}} should
> be used to validate the absence of relative components before any operation
> is done on those paths. This is missed in all the {{initialize*()}}
> functions, as Hemanth pointed out offline.
