Can't find spark application output

I have a cluster that I can launch successfully, at least that's what appears on web UI in which I see this information

URL: spark://Name25:7077
REST URL: spark://Name25:6066 (cluster mode)
Alive Workers: 10
Cores in use: 192 Total, 0 Used
Memory in use: 364.0 GB Total, 0.0 B Used
Applications: 0 Running, 5 Completed
Drivers: 0 Running, 5 Completed
Status: ALIVE

I used submit command to run my application, if I use it in this way

./bin/spark-submit --class myapp.Main --master spark://Name25:7077 --deploy-mode cluster /home/lookupjar/myapp-0.0.1-SNAPSHOT.jar /home/etud500.csv  /home/

I get this message :

Running Spark using the REST application submission protocol. Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties 16/08/31 15:55:16 INFO RestSubmissionClient: Submitting a request to launch an application in spark://Name25:7077. 16/08/31 15:55:27 WARN RestSubmissionClient: Unable to connect to server spark://Name25:7077.

and if I use it in this way :

./bin/spark-submit --class myapp.Main --master spark://Name25:6066 --deploy-mode cluster /home/lookupjar/myapp-0.0.1-SNAPSHOT.jar /home//etud500.csv  /home/result

I get this message

I think it's a success but my application should have 3 outputs to the given path (/home/result), because I used in my code :

path =args [1];
rdd1.saveAsTextFile(path+"/rdd1");
rdd2.saveAsTextFile(path+"/rdd2");
rdd3.saveAsTextFile(path+"/rdd3");

Question 1 : Why does it ask me to use "spark://Name25:6066 " rather than "spark://Name25:7077 "? because according to spark website we use :7077

Question 2 : If it indicates success of submitting and completed applications, why don't I find the 3 output folders ?

Submitting using 6066 does NOT indicate that your job is successfully completed. It just sends request, the job is running in background. You have to check on spark UI for the status of job completion.

If the job is completed and your job generated output files, you can check your file using:
