Submitting Jobs and Applications to the Cluster
You can submit YARN applications (MapReduce version 2 and other applications that run on YARN) to the same cluster. An application can be submitted to the cluster in the following ways:
- The
hadoop jar
command submits an MRv2 application. - The
yarn jar
command submits an application. - An external application submits an application.
- An ecosystem component generates and submits an application.
- The
hadoop job
command submits an MRv2 application. - The
mapred job
command submits an MRv2 application.
When you submit a non-MapReduce application to the cluster, such a Spark application, it is
automatically processed using yarn
mode (ResourceManager, NodeManager, and
MapReduce ApplicationMaster).
NOTE
The method to submit Hadoop commands from a Windows or Mac client is different, For
details, see Setting Up the
Client.
