Databricks

Hi there!

I hope u are doing well

I'm trying to start a cluster with a docker image to install all the libraries that I have to use.

I have the following Dockerfile to install only python libraries as you can see

FROM databricksruntime/standard
WORKDIR /app
COPY . .
RUN apt-get update && apt-get install -y python3-pip
RUN sudo apt-get install -y libpq-dev
RUN pip install -r /app/requirements.txt
CMD ["python3"]

Does anybody knows how to install maven libraries from this same Dockerfile? I've tried and looked up for many solutions but I can't figure it out how to do that.

The last thing I've had tried is to use a Multi stage building using the Maven image but I had trouble with the dependencies (missing POM.xml file).

# MAVEN + PYTHON
 
FROM databricksruntime/standard
WORKDIR /app
COPY . .
RUN apt-get update && apt-get install -y python3-pip
RUN sudo apt-get install -y libpq-dev
RUN pip install -r /app/requirements.txt
CMD ["python3"]
 
FROM maven:latest
WORKDIR /root
COPY --from=0 /app .
 
RUN mvn clean install org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=https://mvnrepository.com/artifact/com.crealytics/spark-excel_2.12/0.14.0 \
    -Dartifact=com.crealytics:spark-excel_2.12:0.14.0
 
RUN mvn clean install org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=https://mvnrepository.com/artifact/mysql/mysql-connector-java \
    -Dartifact=mysql:mysql-connector-java:8.0.29

I don't get it how to install maven libraries from Dockerfile

If someone has knowledge about something like this and could help me I will appreciate it a lot.

Thanks!

Hi @Ignacio Guillamondegui, This is an excellent S.O discussion on the topic you've raised a query on. Please let us know if that helps.

Thanks! I have tried some answers from the S.O discussion and I could build the image but I can't run it.

I can build the image using the flag dependency:solve

But still can't install it, when I have to run it I receive the next message, so the cluster can't start

Anyways, I'm grateful about your answer because it was very useful to keep learning about how to resolve this issue, I appreciate that

1) Install your jars in a new layer, not in the same layer

2) installing with maven is more work than building the library in your jar layer

Hi! I am facing a similar issue.

I tried to use this one

FROM databricksruntime/standard:10.4-LTS
 
ENV DEBIAN_FRONTEND=noninteractive
RUN apt update && apt install -y maven && rm -rf /var/lib/apt/lists/*
 
RUN /databricks/python3/bin/pip install databricks-cli
 
RUN mkdir /databricks/jars
 
RUN mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:get -Dartifact=com.microsoft.azure.kusto:kusto-spark_3.0_2.12:2.5.2 -Ddest=/databricks/jars/
 
RUN /databricks/python3/bin/pip install azure-kusto-data==2.1.1

But it looks like it doesn't work. I get an error java.lang.NoClassDefFoundError: com/microsoft/azure/kusto/data/exceptions/DataServiceException

And if I install libraries using an interface like on the picture - everything works.
