-For lazy people who hate to execute a Zeppelin notebook that doesn't work for unknown reasons!

+For lazy people who hate to execute a Zeppelin notebook that doesn't work for unknown reasons!
+
+# How it works?
+Let's say you want to create a series of spark jobs to evaluate some features in your datasets. You have to use a Zeppelin notebook.
+Sometimes the notebook doesn't work well. You don't understand why you have such errors instead in spark-shell works.
+
+with this new project your problem are done.
+
+## step 1
+Create a Java/Scla main application where run your stuff
+
+## step 2
+Run the python script
+
+`python execute_notebook.py {SSH USER NAME} {MAIN CLASS reference path} {arguments_file path}`
+
+the arguments_file is a file which contains all the arguments organized one for line.
+
+This script does the following:
+ 
+- create the main jar using mvn package
+- upload the jar to the iss machine (_iis-cdh5-test-gw.ocean.icm.edu.pl_)
+- upload all the dependencies jar by checking in the pom those preceded by comment `<!-- JAR NEED -->`
+- submit the spark-job and you can watch the output log directly on your machine
+
+That's AWESOME!
