I am newbie to Apache Spark and Cluster Computing and I implemented Spark in Standalone Mode (Same Machine with Master and Worker), it worked fine for me.
Then, I downloaded pre-built version of spark, and followed these instructions and placed in every nodes of my cluster: http://spark.apache.org/docs/latest/spark-standalone.html#installing-spark-standalone-to-a-cluster.
My Master node has IP address: 172.17.0.224 and my Slave nodes has IP Address: 172.17.0.221, 172.17.0.222 and 172.17.0.223.
And I edited slaves and spark-env.sh files to add the IP addresses of my slaves and IP address of my master respectively.
I started the master node start-master.sh and started the slave nodes with start-slaves.sh, everything worked fine.
I submitted my spark-job using the command spark-submit --class "Rice" --master spark://172.17.0.224:7077 cs453project/target/scala-2.11/simple-project_2.11-1.0.jar cs453project/input.txt cs453project/ouput2 cs453project/ouput3.
This is the error messages I got:

Could you please help me understand how can I solve my problem? Thanks!
The path you used is probably only local to the driver. You have to use a path that is accessible to all of the workers. The driver does not send the actual data to the workers - that would be unfortunately slow. The workers will try to read the data using the path you gave them. In this case, they will fail because the don't have the files locally.
#user3180835, as suggested by #Mike Park, in my case, after I copied the file from local linux file system to hdfs, it started working.
hdfs dfs -cp file:///<path_to_local_file> /<hdfs_file_dir>

I've tried to run my own Pregel method for a relatively small graph (250k vertices, 1.5M edges). The algorithm which I use may (high chances are) be non-convergent meaning in most cases maxIterations setting is actually acting as hard stop finishing all calculations.
I'm using AWS EMR with apache spark and m5.2xlarge instances for all nodes in a setup with EMR-managed scaling. Initially, cluster is set to run 1 master and 4 worker nodes with expansion up to 8 max.
For the same setup of cluster, I was increasing the number of maxIterations gradually from 100 to 500 with step of 100 [100, 200, 300, 400, 500]. I was under the assumption that setup enough for 100 iterations will be also enough for any other number just because not used memory will be freeing up.
However, when I ran a set of jobs with maxIterations increasing from 100 to 500 I found that all jobs with maxIterations > 100 were terminated due to step error. I've checked logs of Spark to find issues and this is what I got:

Am I correct that Pregel doesn't finish 200 or more iterations due to OutOfMemory error on some of the cluster nodes?
If so, how does Pregel work that 100 iterations are not causing it and 200 or 300 are causing? My understand before this issue was that Pregel as many other iterative approaches only 'store' previous and current iteration values and results and iteration by iteration values are changing, but their quantity is not increasing, meaning it is still graph with 250k vertices and 1.5m edges and only messages valid for current iteration are adding up to the heap.
Throughout the log I was not able to find any information on low memory and as seen, there are Gigabytes of it available on each node before it terminates
I've created an environment where I've set up 3 Docker containers, 1 for Airflow using the puckel/docker-airflow image with spark and hadoop additionally installed. The other two containers are basically imitating spark master and worker (used gettyimages/spark Docker image to create this). All 3 containers are connected to each other via a bridge network, so all containers are able to communicate with each other.
What I'm trying to do next is to submit spark job from the Airflow container to the Spark cluster (master).
As an initial example, I'm using the wordcount sample script. I created a sample.txt file in the airflow container at path usr/local/airflow/sample.txt. I've bashed into the Airflow container and I'm using the command given below to run the wordcount.py on spark master located at the ip which I found after inspecting the bridge network.
spark-submit --master spark://ipaddress:7077 --files usr/local/airflow/sample.txt /opt/spark-2.4.1/examples/src/main/python/wordcount.py sample.txt
After submitting the script, from the logs, I can see that a connection has been established with the master (from airflow container), and it also copied the file specified by --files to the master and worker, but then it just errors out saying,
java.io.FileNotFoundException: File file:/usr/local/airflow/sample.txt does not exist
As per my understanding (could be wrong), but when we specify files to copy to master using --files you can access it directly via the file name (sample.txt in my case). So what I'm trying to figure out is if a job has been submitted and the file has been copied to master, then why is it searching in the location file:/usr/local/airflow/sample.txt? How do I make it refer to the correct path?
I apologize as this question has been asked a couple of times, but I've read all the related question on stackoverflow, but I'm still unable to resolve this. I'd really appreciate y'alls help on this.
Thanks.

Change your spark-submit like below for submitting your spark job.
spark-submit \
--master spark://ipaddress:7077 \
--deploy-mode cluster # add this if you want to pass file name to wordcount.py
--files usr/local/airflow/sample.txt \
/opt/spark-2.4.1/examples/src/main/python/wordcount.py sample.txt
OR
spark-submit \

I'm new to Apache Spark and trying to run a simple program on my cluster. The problem is that the driver allocates all tasks to one worker.
I am running as spark stand-alone cluster mode on 2 computers:
1 - runs the master and a worker with 4 cores: 1 used for the master, 3 for the worker. Ip: 192.168.1.101
2 - runs only a worker with 4 cores: all for worker. Ip: 192.168.1.104
this is the code:
public static void main(String[] args) {
SparkConf conf = new SparkConf().setAppName("spark-project");
JavaSparkContext sc = new JavaSparkContext(conf);
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
JavaRDD<String> lines = sc.textFile("/Datasets/somefile.txt",7);
System.out.println(lines.partitions().size());
Accumulator<Integer> sum = sc.accumulator(0);
JavaRDD<Integer> numbers = lines.map(line -> 1);
System.out.println(numbers.partitions().size());
numbers.foreach(num -> System.out.println(num));
numbers.foreach(num -> sum.add(num));
System.out.println(sum.value());
sc.close();
}
Note: used Thread.sleep() command because I tried this: https://issues.apache.org/jira/browse/SPARK-3100
I used the submit script:
bin/spark-submit --class spark.Main --master spark://192.168.1.101:7077 --deploy-mode cluster /home/sparkUser/JarsOfSpark/JarForSpark.jar
this is the result I have got from the driver stdout:

I also tried to stop one of the workers to see what happens and the program successfully completed on the other worker.
and I looked at this post but unfortunately it didn't solved my problem:
Why my tasks only be done in one worker in Spark cluster
Appreciate your help!
It is because of Data Locality - "How close data is to the code processing it"
Spark tries to schedule the available tasks to its best locality levels.
Spark by default tries "PROCESS_LOCAL" mode as the first option and switches on to the lower levels only if it sees that the none of the CPU's are freed after a certain time interval.
Default wait time before switching to lower levels is 3s (see spark.locality.wait parameter).
And looking at the logs, all your tasks are finished within 3 seconds.

Would suggest to try with larger files (in GB's) where each tasks takes some time to get the final results.
for more information on Data Locality, please read the section "Data Locality" in Spark Tuning Section
I read the section Metrics on spark website. I wish to try it on the wordcount example, I can't make it work.

I run my app in local like in the documentation :
$SPARK_HOME/bin/spark-submit --class "SimpleApp" --master local[4] target/scala-2.10/simple-project_2.10-1.0.jar
I checked /home/spark/Documents/test/ and it is empty.
What did I miss?

I made it work specifying in the spark submit the path to the metrics file
--files=/yourPath/metrics.properties --conf spark.metrics.conf=./metrics.properties
I just started playing with Spark. So I ran the SimpleApp program from tutorial (https://spark.apache.org/docs/1.0.0/quick-start.html), which works fine.
However, if I change the file location from local to hdfs, then I get an EOFException.
I did some search online which suggests this error is caused by hadoop version conflicts, I made the suggested modification in my sbt file, but still get the same error.
I am using CDH5.1, code and full error log is below. Any help is greatly appreciated.
Thanks

val numAs = logData.filter(line => line.contains("a")).count()
val numBs = logData.filter(line => line.contains("b")).count()
