Did you specify -Dscala-2.10
As in
./dev/change-scala-version.sh 2.10 ./build/mvn -Pyarn -Phadoop-2.4 -Dscala-2.10 -DskipTests clean package
If you're building with scala 2.10

what am i forgetting?
once again, last command i launched on the docker file is


RUN ./build/mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package

You have a space between "build" and "mvn"

HI all
 sorry for the partially off-topic, i hope there's someone on the list who has tried the same and encountered similar issuse

Ok so i have created a Docker file to build an ubuntu container which inlcudes spark 2.0, but somehow when it gets to the point where it has to kick off  ./build/mvn command, it errors out with the following

---> Running in 8c2aa6d59842
/bin/sh: 1: ./build: Permission denied
The command '/bin/sh -c ./build mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package' returned a non-zero code: 126

I am puzzled as i am root when i build the container, so i should not encounter this issue (btw, if instead of running mvn from the build directory  i use the mvn which i installed on the container, it works fine but it's  painfully slow)

here are the details of my Spark command( scala 2.10, java 1.7 , mvn 3.3.9 and git have already been installed)

# Spark
RUN echo "Installing Apache spark 2.0"
RUN git clone git://github.com/apache/spark.git
WORKDIR /spark
RUN ./build/mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package


Could anyone assist pls?

kindest regarsd
