Hi all,

 

Itís a while Iím trying to connect to a plasma store via scala.

Iím using the arrow Java API from scala, but if I use the classes in org.apache.arrow.plasma, I cannot reach the host.

I even tried to start the process before attempt to connect from the same program, similarly to:

https://github.com/apache/arrow/blob/master/java/plasma/src/test/java/org/apache/arrow/plasma/PlasmaClientTest.java

 

But I cannot reach the host either way. I post the code I wrote in the following:

 

import java.io.IOException;

import org.apache.arrow.plasma.PlasmaClient;

 

object TestPlasma {

    def main(args: Array[String]) {       

        val builder = new ProcessBuilder("plasma_store", "-m", "268435456", "-s", "test");

        try {

            println(builder.start());

            println("Start process " + " OK");

        } catch  {

            case ex: IOException =>

                ex.printStackTrace();

        }

 

        val plasmaClient = new PlasmaClient("test","",1000);

    }

}

 

From the execution I get:

 

java.lang.UNIXProcess@1b39dcee

Start process  OK

If I try to reach the plasma store I start in the code above with a python script, I reach it without any problem.

 

Thank you in advance and sorry if I write both in dev and user, but I had many problems in subscribing to user, I havenít understood if this mailing list is up and ready or not.
