I have a spark cluster with 4 nodes and i try to start app:
spark-submit --deploy-mode cluster --class "Init" --master spark://host /home/cassandra/spark2Cassandra-assembly-0.1.jar - this doesn't work even if i add this: --jars /home/cassandra/jsr166e-1.1.0.jar
Also, i tried to assembly my app with all dependencies inckuding com/twitter/jsr166e/LongAdder
libraryDependencies += "com.twitter" % "jsr166e" % "1.1.0"
Also, i tried to add this jar into all nodes' spark\jars dir - this didn't work for me
How can i distribute this jar to my cluster?
Full error (the same message many times):

UPDATED
If i use local mode and start it via:
spark-shell --jars /data/tmp/spark-cassandra-connector-2.0.5-s_2.11.jar,/data/tmp/jsr166e-1.1.0.jar
It works, but the same doesn't work for cluster mode
The problem was in SPARK_HOME environment variable which wasn't defined on nodes
