I got a problem when I used sbt to run a spark job, I have finish compile, but when I run the command run, I got the problem below

 [error] (run-main-0) java.lang.NoSuchMethodError: scala.collection.immutable.HashSet$.empty()Lscala/collection/immutable/HashSet;

Anyone knows what should I do?

回答1:

I met with the same error when I used scala-library-2.11 jar But when I replaced it with scala-library-2.10 jar . It runs fine

回答2:

It is probably caused by using incompatible versions of Scala. When I downgraded from Scala 2.11 to 2.10, I forgot to modify one package version (so one package used 2.11, the rest 2.10), resulting in having the same error.

Note: I only had this problem when using IntelliJ.

If you are getting the error and here because you cannot run Jupiter notebooks with Spark 2.1 and Scala 2.11 below is how I was able to make it work. Assumes you installed Jupiter and toree

Pre-req - Make sure Docker is running else Make fails. Make sure gpg is installed else Make fails.

Build steps -

export SPARK_HOME=/Users/<path>/spark-2.1.0-hadoop2.7/ 
git clone https://github.com/apache/incubator-toree.git 
cd incubator-toree 
make clean release APACHE_SPARK_VERSION=2.1.0 
pip install --upgrade ./dist/toree-pip/toree-0.2.0.dev1.tar.gz 
pip freeze |grep toree 
jupyter toree install --spark_home=$SPARK_HOME

========================================================================

To Start the notebook - SPARK_OPTS='--master=local[4]' jupyter notebook

I used these versions and everything works now.

    <dependency>
        <groupId>org.scala-lang</groupId>
        <artifactId>scala-library</artifactId>
        <version>2.11.6</version>
    </dependency>

    <dependency>
        <groupId>com.typesafe.akka</groupId>
        <artifactId>akka-actor_2.11</artifactId>
        <version>2.3.11</version>
    </dependency>

回答5:

Check whether the scala version you are using corresponds to the precompiled spark version.

回答6:

The issue could be reproduced with version 2.11.8.

By the moment, no downgrade is required. Just update scala-library version to 2.12.0.

回答7:

I've the exactly the same problem and got it fixed by downgrading scala 2.11.8 to 2.10.6.

回答8:

I've the same issue but where do i alter the scala-library version?

Installation (on Ubuntu 16.04):

sudo apt-get install oracle-java8-installer
wget http://d3kbcqa49mib13.cloudfront.net/spark-2.0.2-bin-hadoop2.7.tgz && tar xvf spark-2.0.2-bin-hadoop2.7.tgz
pip install toree && jupyter toree install

So when I start with a notebook it tells me that I use a different scala version. But I haven't installed anything else. screenshot + scala version

My spark jars folder contains an scala-library-2.11.8.jar file. But how tell torree to use that (or another) file for scala.
