I want to submit a Spark job on a remote YARN cluster using the spark-submit command. My client is a Windows machine and the cluster is composed of a master and 4 slaves. I copied the Hadoop config files from my cluster to the remote machine, namely core-site.xml and yarn-site.xml and set the HADOOP_CONF_DIR variable in spark-env.sh to point to them.
However, when I submit a job using the following command :
spark-submit --jars hdfs:///user/kmansour/elevation/geotrellis-1.2.1-assembly.jar \
--class tutorial.CalculateFlowDirection hdfs:///user/kmansour/elevation/demo_2.11-0.2.0.jar hdfs:///user/kmansour/elevation/TIF/DTM_1m_19_E_17_108_*.tif \
--deploy-mode cluster \
--master yarn
I get stuck with:
INFO yarn.Client: Application report for application_1519070657292_0088 (state: ACCEPTED)
Until I get this :
diagnostics: Application application_1519070657292_0088 failed 2 times due to AM Container for appattempt_1519070657292_0088_000002 exited with exitCode: 10
For more detailed output, check application tracking page:http://node1:8088/cluster/app/application_1519070657292_0088Then, click on links to logs of each attempt.

The IP address of my master node is 132.156.9.142 and the IP address of my client is 132.156.9.98. The log shows me that the application master is attempting to connect to the driver on the client when I explicitly stated --deploy-mode cluster.
Shouldn't the driver driver be on a node in the cluster ?

I am very new at all this and perhaps my reasoning is flawed, any input or suggestions would help.
