(Updated Dec. 6, 2015, 11:35 p.m.)


Review request for mesos, Ben Mahler, Ian Downes, and Vinod Kone.


Changes
-------

Update the draft code diff to move `getExecutorInfo` from slave to master; but 
there's still some failed cases on slave's registry. Will discuss the solution 
for it in JIRA.


Bugs: MESOS-1718
    https://issues.apache.org/jira/browse/MESOS-1718


Repository: mesos


Description
-------

Currently we give a small amount of resources to the command executor, in 
addition to resources used by the command task: 
https://github.com/apache/mesos/blob/0.20.0-rc1/src/slave/slave.cpp#L2448

```
ExecutorInfo Slave::getExecutorInfo(
    const FrameworkID& frameworkId,
    const TaskInfo& task)
{
  ...
    // Add an allowance for the command executor. This does lead to a
    // small overcommit of resources.
    executor.mutable_resources()->MergeFrom(
        Resources::parse(
          "cpus:" + stringify(DEFAULT_EXECUTOR_CPUS) + ";" +
          "mem:" + stringify(DEFAULT_EXECUTOR_MEM.megabytes())).get());
  ...
}
```

This leads to an overcommit of the slave. Ideally, for command tasks we can 
"transfer" all of the task resources to the executor at the slave / isolation 
level.
