Configuring MapReduce Mode for Ecosystem Service

Some ecosystem clients communicate with the cluster through a service. In this case, the MapReduce mode that is configured for the ecosystem service has a higher priority and cannot be overridden by the client.

By default, the ecosystem service will run MapReduce jobs and applications using the MapReduce mode of the cluster. However, you can set the MapReduce mode for the following ecosystem services:

Hue
Httpsfs
Hiveserver2
Oozie

In the following figure, the Hive client is installed on a client node with a default_mode=yarn and the Hive service is installed on a cluster with default_mode=yarn. However, since the Hive server has a MAPR_MAPREDUCE_MODE=classic, the job is submitted to the JobTracker.
