loic tregan commented on LIVY-593:
----------------------------------
After researching further:
- first set of users will be on Spark 2 (latest currently 2.4.8): it is
based on Scala 2.11; build output of Spark says:
exec: curl --progress-bar -L
[https://downloads.lightbend.com/scala/2.11.12/scala-2.11.12.tgz]
- second set of users will be on Spark 3 (latest currently 3.2.2): it is
based on Scala 2.12; build output of Spark says:
exec: curl --silent --show-error -L
[https://downloads.lightbend.com/scala/2.12.15/scala-2.12.15.tgz]
The most conservative / less error-prone option would thus be that 'mvn
package' build both by default.
If for some reason we have to choose one version and cannot do both by default,
then I'd use whatever '$SPARK_HOME/bin/spark-submit --version' returns (which
also would be consistent with what sparkmagic does, as sparkmagic is I guess
the most popular use case for livy-server it'd make sense they have both have
the same strategy).
