Siddharth Seth updated MAPREDUCE-4663:
--------------------------------------
Attachment: MR4663.txt
Removes the ContainerLaunch dependency on Task. Containers still depend on
TaskType though - used in the jvm id and to set up metrics.
Enabling profiling for a container needs to be decided by the scheduler.
Requires MAPREDUCE-4664
> [MAPREDUCE-3902] Container Launch should be independent of o.a.h.m.Task

> Since a container/JVM can be used across TaskAttempts - launching the jvm
> should not depend on an individual task.
