------------------------------------
Summary: Explore disk io isolation in cgroups
Key: MESOS-350
URL: https://issues.apache.org/jira/browse/MESOS-350
Project: Mesos
Issue Type: Improvement
Reporter: Sathya Hariesh
Currently there is no disk isolation in place and this affects an executor to
be starved of disk when another disk heavy operation such as copying a multi
gigabyte file is being performed by another executor.
At Twitter, the executor performs a few fsync operations and has specific wait
periods for these operations to succeed. When these operations take longer than
expected during termination of tasks, it would potentially result in LOST tasks.
