Why do you need Java 11 bytecode though?
Java 8 bytecode runs fine on Java 11. The settings in the build are really
there for testing, not because it's required to use Java 11.

Bytecode version is controlled by javac "-target" option for Java, and by
scalac "-target:" for Scala
JDK can cross-compile between known versions.
Spark uses 1.8 as source and target by default controlled by the Maven
property java.version
Ok, so I used a docker image `adoptopenjdk/openjdk11:latest` as a builder,
and still got version 52 classes.

Thank you - looks like it COULD do it.
Have to try if I can have a simple UI, user selects one out of 100 options, and
receives the correct x/y plot and correct histogram of data stored in hive and
retrieved with spark into pandas…
Many thanks for your suggestion!

Sure, look at any python-based plotting package. plot.ly does this nicely.
You pull your data via Spark to a pandas DF and do whatever you want.

Hi,
I am making a very short demo and would like to make the most rudimentary UI
(withouth knowing anything about front end) that would show a x/y plot of data
stored in HIVE (that I typically query with spark) together with a histogram
(something one would typically created in a jupyter
Increase the stack size for the JVM when Maven / SBT run. The build sets
this but you may still need something like "-Xss4m" in your MAVEN_OPTS

Hi Sergey,
I’m willing to be corrected, but I think the use of a JAVA_HOME environment
variable was something that was started by and continues to be perpetuated by
Apache Tomcat.
… or maybe Apache Ant, but modern versions of Ant do not need it either.
It is not needed for modern releases of
Hi Steve,
Can you shed some light why do they need $JAVA_HOME at all if everything is
already in place?
