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
Scala:
/* SimpleApp.scala */
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
object SimpleApp {
def main(args: Array[String]) {
val logFile = "hdfs://plogs001.sjc.domain.com:8020/tmp/data.txt" // Should be some file on your system
val conf = new SparkConf()
.setMaster("spark://plogs004.sjc.domain.com:7077")
.setAppName("SimpleApp")
.set("spark.executor.memory", "1g")
val sc = new SparkContext(conf)
//val logFile = "/tmp/data.txt" // Should be some file on your system
//val conf = new SparkConf().setAppName("Simple Application")
//val sc = new SparkContext(conf)
val logData = sc.textFile(logFile, 2).cache()
val numAs = logData.filter(line => line.contains("a")).count()
val numBs = logData.filter(line => line.contains("b")).count()
println("Lines with a: %s, Lines with b: %s".format(numAs, numBs))
}
}

I am setting up a local Spark instance on Windows to use with PySpark as described in this guide (but with spark-3.0.0 / hadoop 2.7 instead): https://phoenixnap.com/kb/install-spark-on-windows-10.
I can startup Spark with:
C:\Spark\spark-3.0.0-bin-hadoop2.7\bin>spark-shell.cmd
and connect to it with http://localhost:4040/ in my browser (I see the Spark GUI).
But when am running the Python pyspark example with
C:\Spark\spark-3.0.0-bin-hadoop2.7\examples>run-example SparkPi
it throws an Permission Denied error like in this trace:

At first it seemed to me as a Firewall issue, but adding the executing java.exe as exeption to the firewall didn't solve the issue.
Does anyone know what I should try next to get this issue resolved?
Finally I could solve it by setting my SPARK_LOCAL_IP to localhost in my environment variables: Go to your Windows environment variables and set SPARK_LOCAL_IP=localhost
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 \

I am developing a test application in Intellij using scala and spark cassandra connector. Here is my build.sbt code:
scalaVersion := "2.11.8"
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.6.1"
libraryDependencies += "org.apache.spark".%%("spark-sql") % "1.6.1"
libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector" % "1.6.0-M2"
I have created cassandra cluster using ccm with 4 nodes. The keyspace I created has replication factor 3. Here is my code in scala app
val conf = new SparkConf()
.setMaster("local[*]")
.setAppName("SparkCassandra")
//set Cassandra host address as your local address
.set("spark.cassandra.connection.host", "127.0.0.1")
val sc = new SparkContext(conf)
val rdd = sc.cassandraTable("excelsior", "emp")
val total = rdd.count()
println(total)
println("exiting now:")
sc.stop()
But the spark job hangs at following line
CassandraConnector: Disconnected from Cassandra cluster: cluster4nodes
Only 3 tasks out of 4 are completed.Here is the full log:

If I created a keyspace with replication factor 4 on 4 nodes cluster, app works fine and never hangs. Am I missing anything in configuration. Thanks in advance.
My codes are as below:
object WordCount extends App{
val conf = new SparkConf().setAppName("WordCount").setMaster("spark://sparkmaster:7077")
val sc = new SparkContext(conf)
sc.addJar("/home/found/FromWindows/testsSpark/out/artifacts/untitled_jar/untitled.jar")
val file = sc.textFile("hdfs://192.168.1.101:9000/Texts.txt")
val count = file.flatMap(line => line.split(" ")).map(word => (word,1)).reduceByKey(_+_)
val res = count.collect()
res.foreach(println(_))
}
When I run it as local mode,everything is OK.However,when running it on cluster,it would crash.I have got the following error messages:

Really puzzled about this, any good idea solving this?
My cluster environment is:Spark 1.5.1/hadoop 2.5.2/scala 2.10.4/jdk1.7.0_51.
My guess is that sc.addJar("/home/found/FromWindows/testsSpark/out/artifacts/untitled_jar/untitled.jar") fails on your executor, because that path / jar does not exist on the executor node. Try putting the jar into HDFS and using an HDFS path to specify it, so that your executors have access to it.
Or even better, use the --jars comand line option to spark-submit and specify your jar there, and then you don't have to change your code and recomple when you change your jar.
The problem has been solved.The main reason is that my project have imported two versions of scala(one extra version from sbt downloading).Thanks for guys who helped me solving this problem.
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>
