Marcelo Vanzin created SPARK-25682:
--------------------------------------
Summary: Docker images generated from dev build and from dist
tarball are different
Key: SPARK-25682
URL: https://issues.apache.org/jira/browse/SPARK-25682
Project: Spark
Issue Type: Bug
Components: Kubernetes
Affects Versions: 2.4.0
Reporter: Marcelo Vanzin
There's at least one difference I noticed, because of this line:
{noformat}
COPY examples /opt/spark/examples
{noformat}
In a dev build, "examples" contains your usual source code and maven-style
directories, whereas in the dist version, it's this:
{code}
cp "$SPARK_HOME"/examples/target/scala*/jars/* "$DISTDIR/examples/jars"
{code}
So the path to the actual jar files ends up being different depending on how
you built the image.
