If the default MapR ticket location, /tmp/maprticket_<uid>, has been changed, set MAPR_TICKETFILE_LOCATION environment variable accordingly in the machine in which your Job is executed.

As MapR does not provide any API to specify a MapR ticket, setting the environment variable is the only way to use a custom MapR ticket location in your Job. For further information about this issue, see this post from the MapR forum.

This procedure is necessary only when you are storing the MapR tickets in a custom location. If you use the default MapR ticket location, skip this procedure.
