-----------------------------
Summary: ContainerLogger might leak FD if container launch fails.
Key: MESOS-6632
URL: https://issues.apache.org/jira/browse/MESOS-6632
Project: Mesos
Issue Type: Bug
Affects Versions: 1.0.1, 0.28.2, 1.1.0
Reporter: Jie Yu
Priority: Critical
In MesosContainerizer, if logger->prepare() succeeds but its continuation
fails, the pipe fd allocated in the logger will get leaked. We cannot add a
destructor in ContainerLogger::SubprocessInfo to close the fd because
subprocess might close the OWNED fd.
A FD abstraction might help here. In other words, subprocess will no longer be
responsible for closing external FDs, instead, the FD destructor will be doing
so.
