A. Myriad renames the hadoop distro file to binary.tgz

Q. Why do I get this download error?

...

The other possibility is that the relative local directory path to the binary.tgz file–in this case, dist/hadoop-2.6.0.tgz–either does not exist or the directory from which you are launching the resource manager is not $YARN_HOME directory. For the former, create the directory and place the config.tgz and binary.tgz (again, in this case, hadoop-2.6.0.tgz) in that directory.  For the latter, cd to $YARN_HOME and then launch the Resource Manager via bin/yarn resourcemanager. 

Q. I have passwordless sudo for the frameworkUser and/or my frameworkUser is root, so why am I getting this error:

...

sudo su root
visudo

Q, How do I examine the command Mesos uses to launch a YARN Resource Manager via a Myriad executor?

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.
