Changes
-------
Reverted adoption of Subprocess due to multiple issues arising out of its use.
Summary (updated)
-----------------
Added External Containerizer.
Bugs: MESOS-816
https://issues.apache.org/jira/browse/MESOS-816
Repository: mesos-git
Description
-------
This patch adds the so-called external containerizer. This
containerizer delegates all containerizer calls directly to
an external containerizer program (which can be specified on
start-up). Few calls have internal fall-back implementations
such as wait(), destroy() and usage().
The protocol for the interactions with the external program
is as follows:
COMMAND (ADDITIONAL-PARAMETERS) < INPUT-PROTO > RESULT-PROTO
launch (ContainerID, --mesos-executor, <path>) < TaskInfo > ExternalStatus
update (ContainerID) < ResourceArray > ExternalStatus
usage (ContainerID) > ResourceStatistics
wait (ContainerID) > ExternalTermination
destroy (ContainerID) > ExternalStatus
When protocol buffers need to be provided, the Mesos side of
the external containerizer implementation will serialize the
protos on stdin and vice-versa for reading protos on stdout as
drafted in the above scheme.
