Per my knowledge, with Marathon/Chronos framework, applications can be deployed to slave nodes that fulfill their resource requirement. But I can't find any information on if those applications fail for internal defects, then if application developer or support engineer can logon the node to do diagnostic work? Collecting log file etc.

I mean on mesos. If can't log on node host, then how to get log file for defect investigation. Thanks. – Zhang Yong Ming Jul 25 '15 at 03:30

Regarding cloud native apps, logging service should be used to record what happened instead of local log file. I just read Oreilly book Migrating to Cloud Native application Architecture, quoted a paragraph as below:
Logs Rather than managing logfiles, treat logs as event streams, allowing the execution environment to collect, aggregate, index, and analyze the events via centralized services.
