I have a Spark Master and Worker running on a remote Ubuntu Linux machine.
I'm trying to run the JavaDirectKafkaWordCount example.
But when I submit from my Windows machine to the Linux cluster I get
C:/spark-1.6.0-bin-hadoop2.6/bin/spark-submit --master spark://10.123.45.67:6066 --deploy-mode cluster --class com.company.spark.app.JavaDirectKafkaWordCount "C:/Dev/spark-app/target/spark-app-1.0-SNAPSHOT.jar" kafka-server:9092 topic1
Running Spark using the REST application submission protocol.

It looks like Spark is taking C: as the schema. Try changing to
C:/spark-1.6.0-bin-hadoop2.6/bin/spark-submit --master spark://10.123.45.67:6066 --deploy-mode cluster --class com.company.spark.app.JavaDirectKafkaWordCount "file:///C:/Dev/spark-app/target/spark-app-1.0-SNAPSHOT.jar" kafka-server:9092 topic1
By adding file:/// to the file path you are telling Spark that the schema is file, so it will not get confused and use C as the schema. Jars submitted to spark using file should get hosted by spark so the cluster can see them.
The application jar file you input at the submit command use the windows location, but according for the spark official document:
application-jar: Path to a bundled jar including your application and all dependencies. The URL must be globally visible inside of your cluster, for instance, an hdfs:// path or a file:// path that is present on all nodes.
So the file must be exist or accessible from each of the cluster member, if use the local file system, you must make sure the file exist at very node.
At my local environment, I use the file:///opt/spark-2.0.1-bin-hadoop2.7/examples/jars/spark-examples_2.11-2.0.1.jar, it can pass the test.

Please advise. Thanks in advance!
The ~/.aws/credentials file located in the home directory of the operating system user that runs the Connect worker processes. These credentials are recognized by most AWS SDKs and the AWS CLI. Use the following AWS CLI command to create the credentials file:
aws configure
You can also manually create the credentials file using a text editor. The file should contain lines in the following format:
[default]
aws_access_key_id =
aws_secret_access_key =
NOTE : When creating the credentials file, make sure that the user creating the credentials file is the same user that runs the Connect worker processes and that the credentials file is in this user's home directory. Otherwise, the S3 connector will not be able to find the credentials.
Using win7-64, jdk8, sparks1.6.2.
I have spark running, winutils, HADOOP_HOME, etc
Per documentation Note: The launch scripts do not currently support Windows. To run a Spark cluster on Windows, start the master and workers by hand. But does not say how?
How do I launch spark master on windows?
Tried running sh start-master.sh thru git bash : failed to launch org.apache.spark.deploy.master.Master: Even though it prints out Master --ip Sam-Toshiba --port 7077 --webui-port 8080 - So I don't know what all this means.
But when I try spark-submit --class " " --master spark://Sam-Toshiba:7077 target/ .jar -
I get errors:
WARN AbstractLifeCycle: FAILED SelectChannelConnector#0.0.0.0:

Also tried spark://localhost:7077 - same errors
On Windows you can launch Master using below command. Open command prompt and go to Spark bin folder and execute
spark-class.cmd org.apache.spark.deploy.master.Master
Above command will print like Master: Starting Spark master at spark://192.168.99.1:7077 in console as per IP of your machine. You can check the UI at http://192.168.99.1:8080/
If you want to launch worker once your master is up you can use below command. This will use all the available cores of your machine.
spark-class.cmd org.apache.spark.deploy.worker.Worker spark://192.168.99.1:7077
If you want to utilize 2 cores of your 4 cores of machine then use
spark-class.cmd org.apache.spark.deploy.worker.Worker -c 2 spark://192.168.99.1:7077
I used the following command to run the spark java example of wordcount:-
time spark-submit --deploy-mode cluster --master spark://192.168.0.7:7077 --class org.apache.spark.examples.JavaWordCount /home/pi/Desktop/example/new/target/javaword.jar /books_500.txt
I have copied the same jar file into all nodes in the same location. (Copying into HDFS didn't work for me.) When I run it, the following is the output:-

It just stops there, quits the job and waits for the next command on terminal. I didn't understand this error without an error message. Help needed please...!!
I am trying to run a simple Map/Reduce java program using spark over yarn (Cloudera Hadoop 5.2 on CentOS). I have tried this 2 different ways. The first way is the following:
YARN_CONF_DIR=/usr/lib/hadoop-yarn/etc/hadoop/;
/var/tmp/spark/spark-1.4.0-bin-hadoop2.4/bin/spark-submit --class MRContainer --master yarn-cluster --jars /var/tmp/spark/spark-1.4.0-bin-hadoop2.4/lib/spark-assembly-1.4.0-hadoop2.4.0.jar simplemr.jar
This method gives the following error:

changed on src filesystem (expected 1434549639128, was 1434549642191
Then I tried without the --jars:

I tried deleting all the .jars from hdfs://users//.sparkStaging and resubmitting but that didn't help.
The problem was solved by copying spark-assembly.jar into a directory on the hdfs for each node and then passing it to spark-submit --conf spark.yarn.jar as a parameter. Commands are listed below:
hdfs dfs -copyFromLocal /var/tmp/spark/spark-1.4.0-bin-hadoop2.4/lib/spark-assembly-1.4.0-hadoop2.4.0.jar /user/spark/spark-assembly.jar
/var/tmp/spark/spark-1.4.0-bin-hadoop2.4/bin/spark-submit --class MRContainer --master yarn-cluster --conf spark.yarn.jar=hdfs:///user/spark/spark-assembly.jar simplemr.jar
If you are getting this error it means you are uploading assembly jars using --jars option or manually copying to hdfs in each node.
I have followed this approach and it works for me.
In yarn-cluster mode, Spark submit automatically uploads the assembly jar to a distributed cache that all executor containers read from, so there is no need to manually copy the assembly jar to all nodes (or pass it through --jars).
It seems there are two versions of the same jar in your HDFS.
Try removing all old jars from your .sparkStaging directory and try again, it should work.
I've been trying to make this work with no luck thus far. I launch a cluster with
./spark-ec2 -k keyname -i ~/.keys/key.pem --region=us-east-1 -s 5 launch "my test cluster"
Then I submit a job with
bin/spark-submit --verbose --class com.company.jobs.AggregateCostDataWorkflow --master spark://ec2-54-157-122-49.compute-1.amazonaws.com:7077 --deploy-mode cluster --conf spark.executor.memory=5g /Users/my.name/scala-proj/target/scala-2.10/scala-proj-0.1.0.jar --outputPath,s3n://my-bucket/my-name/ec2-spark-test/
Where outPutPath is an argument to the main method. After a bit and some status output, I see an exception that looks like

This is spark 1.3.1 (on my local machine) I can access the UI on the master machine and verify that the Spark processes are in fact up. I can also ssh into the master.
Any tips?
You need to open ports by editing security policies, if you want to access ports on your EC2 spark cluster. spark_ec2.py doesn't open ports 7077 and 6066 on master to be accessed from outside the cluster.
I use the other way - connect to master machine of your spark cluster with the command
./spark_ec2.py -k keyname -i ~/.keys/key.pem login "my test cluster"
Upload the your job file (with scp using same key) and submit job from there. This would ensure that your driver has access to a cluster master and slaves.
See "Running Applications" section of Running Spark on EC2 documentation
