A. In analogy to all Mesos tasks, navigate to the Active Tasks panel from the Myriad Framework page, click on the Myriad task, and then select stdout. The stdout window contains the command that launches the Mesos task corresponding to the YARN Resource Manager and Myriad executor.
Q. Why do I get this max memory error:

A. This means that all of the Myriad tasks--NodeManagers–are allocated less RAM than the either the default mapreduce.map.memory.mb (1024) or the value of this parameter specified in the mapred-site.xml.
