    Full support for MapR 5.1 seems to be implemented as of Datameer version 5.11.17. 

    The message 

    /default-rack UNHEALTHY maprdemo 

    indicates that a node or service from the sandbox environment might not have started and could be related to memory resources. 

    The host computer should have at least 16 GB RAM, since the MapR sandbox requires 6GB, the edge node should also have 6GB and the host OS will need also some memory. 

    Can you run any job in your MapR sandbox? 

    It could also be helpful to check the value of 

    yarn.nodemanager.resource.memory-mb

    which is the Amount of physical memory, in MB, that can be allocated for containers.
