Hi Sophia,

In yarn-client mode, the node that submits the application can either be inside or outside of the cluster. This node also hosts the driver (SparkContext) of the application. All the executors, however, will be launched on nodes inside the YARN cluster.

As the yarn-client mode,will spark be deployed in the node of yarn? If it is
deployed only in the client,can spark submit the job to yarn?
