Configuring the Default MapReduce Mode on Client Nodes
About this task
Procedure
-
Open the hadoop_version file in the following location:
/opt/mapr/conf/
-
Edit the default_mode parameter. The following values are valid for the
default_mode parameter:
Settings Description default_mode=classic
Specifies that the client submits MapReduce v1 jobs to the cluster. default_mode=yarn
Specifies that the client submits MapReduce v2 applications to the cluster. NOTE: The MapReduce mode setting on the client node enables all of the hadoop command that you run on this client to operate using the hadoop version associated with that mode. For example, if you set the MapReduce mode to yarn, when you run hadoop classpath the classpath associated with hadoop 2.x displays.
