(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.
