["Bhuvan Arumugam (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/MESOS-3724?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bhuvan Arumugam updated MESOS-3724:
-----------------------------------
    Description: 
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.

Here is a sample failure: http://pastebin.com/w1Ty41rb
