Key: MESOS-3724
URL: https://issues.apache.org/jira/browse/MESOS-3724
Project: Mesos
Issue Type: Bug
Components: slave
Affects Versions: 0.21.1
Reporter: Bhuvan Arumugam
When running a task with docker and if {{docker inspect}} output size is more
than 64k, it fails. The {{docker inspect}} The subprocess library [1] used in
mesos to run this command is not handling the output beyond this size.
{code}
docker pull livecipher/mesos-docker-inspect-64k:1.0 > /dev/null && docker
inspect livecipher/mesos-docker-inspect-64k:1.0 > inspect.out && du -sh
inspect.out && rm -f inspect.out
76K inspect.out
{code}
You can reproduce it using the above image with any framework. I tested it with
aurora.
