MapR non-standard Hadoop security not supported

Hi guys,

I am sorry if it's a dummy/repeated question. We have been trying to follow the example to bring up dask on yarn and keep getting error "Kerberos ticket not found, please kinit and restart" even though the user starting the cluster does have a valid ticket.

Is there anywhere where I could specifically point to the ticket location at the runtime of the cluster? We have a hadoop cluster and wanted to use dask on yarn. Wondering if anybody has tried to work with this constellation. MapR hadoop cluster/ Dask on Yarn and could give us any pointers would be highly appreciated.

Thank you!
Andre
