I am using Spark 1.5 on Windows. I haven't installed any separate binaries of Hadoop.
I running a Master and a single worker.
It's a simple HelloWorld Program as below :

//tried many combinations above but all gives error.

inputRDD.foreach(new VoidFunction<String>() {

I am new to Hadoop and Java. I have to read and write to a *.txt file stored on HDFS in my remote cloud-era distribution. And for the same I have this small java program written:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URI;

Configuration configuration = new Configuration();
FileSystem hdfs = FileSystem.get( new URI( "hdfs://admin:H4d00p#172.16.10.124:8888" ), configuration );
Path file = new Path("hdfs://admin:H4d00p#172.16.10.124:8888/user/admin/Data/Tlog.txt");
try{
BufferedReader br=new BufferedReader(new InputStreamReader(hdfs.open(file)));
String line;
line=br.readLine();
while (line != null){
System.out.println(line);
line=br.readLine();
}
}catch(Exception e){

}
}
}
But when the row BufferedReader br=new BufferedReader(new InputStreamReader(hdfs.open(file))); is executed I am running into this error:

Could someone help me out to get this resolved please ? I am on this for a day now.
I figured out the solution for this error. And looks like I was using the wrong port. I was using the port number as I see on HUE URL ( misleaded from different sources).
If I chose the port number as defined for the configuration "NameNode Service RPC Port" OR "dfs.namenode.servicerpc-address" on the name node from Cloudera manager, it works fine.
I am trying to get a CSV from the report using this well-known plugin and the example from its documentation, but it throws an exception. I wonder why, because I just copied most of the code from the doc.

I found the package org.eclipse.core.runtime and registered in the build path, but then I am getting the same exception. Indeed, there are no any CoreException.class in the org.eclipse.core.runtime package. What am I doing wrong?
Setting the engine home is deprecated and most of the time it will prevent the Platform to start, such in your case. Remove this line:
config.setEngineHome("C:\\birtre\\birt-runtime-4_3_2\\");
You just have to ensure the birt runtime 4.3.2 is in the classpath of your context. Furthermore i would recommend you try to generate a native format such pdf first, and then try with a csv format.
I was trying a lot of variants of importing different jars, but finally i found the weird decision here:
go to the Project Explorer, right-mouse click on properties for the
project, go to Java Build path, Click on the External Jars button,
then select all the libraries under
C:\birt_runtime\birt-runtime-2_1_0\ReportEngine\lib\ folder
This made chaos there, but at least it starts.
I am trying to call the "dspdf.exe" inside the jar file where this smartpdf class exists. I plan to extract it to a temp location and delete when program ends. However this doesn't seem to work, any help will be appreciated.
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import org.omg.CORBA.portable.InputStream;
public class smartpdf {
static String url="";
static String output="output.pdf";
public static void main(String[] args) throws IOException{
gui mygui = new gui();//gui will call the generate function when user selects
}
public static void generate() throws IOException{
InputStream src = (InputStream) smartpdf.class.getResource("dspdf.exe").openStream();
File exeTempFile = File.createTempFile("dspdf", ".exe");
FileOutputStream out = new FileOutputStream(exeTempFile);
byte[] temp = new byte[32768];
int rc;
while((rc = src.read(temp)) > 0)
out.write(temp, 0, rc);
src.close();
out.close();
exeTempFile.deleteOnExit();
Runtime.getRuntime().exec(exeTempFile.toString()+" "+url+" "+output );
//Runtime.getRuntime().exec("dspdf "+url+" "+output);
}
}

You use the wrong InputStream. Change it to java.io.InputStream.
Why do you use org.omg.CORBA.portable.InputStream instead of a java.io.BufferedInputStream`
with as parameters the inputstream from the resource. I mean this:
BufferedInputStream inputstream = new BufferedInputStream(smartpdf.class.getResourceAsStream(...));
The same for your fileoutput stream: BufferedOutputStream
Don't use
class.getResource(...).openStream();
but use
class.getResourceAsStream(...);
Note also (once you've resolved the InputStream issue) that you should be consuming your spawned process stdout and stderr, otherwise the spawned process may block. See this answer for more details.
