the total memory of your machine is 2G right?then how much memory is 
left free? wouldn`t ubuntu take up quite a big portion of 2G?
just a guess!

Hi, thanks for all your help.

I tried your setting in the sbt file, but the problem is still there.



The Java setting in my sbt file is:

java \

  -Xmx1200m -XX:MaxPermSize=350m -XX:ReservedCodeCacheSize=256m \

  -jar ${JAR} \

  $@



I have tried to set these 3 parameters bigger and smaller, but nothing

works. Did I change the right thing?



Thank you very much.

Re: sbt/sbt run command returns a JVM problem

[Michael Armbrust]

The problem is probably not with the JVM running sbt but with the one that
sbt is forking to run your program.

See here for the relevant option:
https://github.com/apache/spark/blob/master/project/SparkBuild.scala#L186

You might try starting sbt with no arguments (to bring up the sbt console).
 You can then set javaOptions += -Xmx1G and afterwards try run.

Re: sbt/sbt run command returns a JVM problem

[Carter]

Hi Michael,

Thank you very much for your reply.

Sorry I am not very familiar with sbt. Could you tell me where to set the
Java option for the sbt fork for my program? I brought up the sbt console,
and run set javaOptions += -Xmx1G in it, but it returned an error: 
[error] scala.tools.nsc.MissingRequirementError: object scala not found.
[error] Use 'last' for the full log.

Is this the right way to set the java option? Thank you very much.

sbt/sbt run command returns a JVM problem

[Carter]

Hi, I have a very simple spark program written in Scala:
/*** testApp.scala ***/
object testApp {
  def main(args: Array[String]) {
println(Hello! World!)
  }
}
Then I use the following command to compile it:
$ sbt/sbt package
The compilation finished successfully and I got a JAR file.
But when I use this command to run it:
$ sbt/sbt run
it returned an error with JVM:
[info] Error occurred during initialization of VM 
[info] Could not reserve enough space for object heap 
[error] Error: Could not create the Java Virtual Machine. 
[error] Error: A fatal exception has occurred. Program will exit. 
java.lang.RuntimeException: Nonzero exit code returned from runner: 1   
at scala.sys.package$.error(package.scala:27)

My machine has 2G memory, and runs on Ubuntu 11.04. I also tried to change
the setting of java parameter (e.g.,  -Xmx, -Xms, -XX:MaxPermSize,
-XX:ReservedCodeCacheSize) in the file sbt/sbt, but it looks like non of the
change works. Can anyone help me out with this problem? Thank you very much.

Re: sbt/sbt run command returns a JVM problem

[Sean Owen]

Here's how I configure SBT, which I think is the usual way:

export SBT_OPTS=-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256m -Xmx1g

See if that takes. But your error is that you're already asking for
too much memory for your machine. So maybe you are setting the value
successfully, but it's not valid. How big?

 You might want to check the memory settings in sbt itself, which its a shell 
 scripts run a java command. I don't have computer at hand, but if you vim or 
 cat the sbt/sbt , you might see the memory settings , you change it to fit 
 your need

 You might also can overwrite the setting by change .sbtopts  without change 
 the script , but google it for sure.
