I have a problem here that I could use some help on.
hive-exechas a dependency onpentahothat doesn't exist in maven central anymore. This is why we have an entry for it inspark-parent'sdependencyManagementsection that excludespentahoviacalcite-core.But the
scopeinspark-parent'sdependencyManagemententry forhive-execiscompile, so if I make ittesthere, which is what it was in YARN, then it fails to match that entry anymore, and thus doesn't inherit the excludes. This shouldn't be a problem, because dependencies in thetestscope aren't transitive, so we should never be trying to fetch the missingpentahodependency. Butsbtbuilds don't seem to recognize this transitivity, so if I add thetestscope, I get this error:What I can't understand is how this wasn't a problem when these dependencies were in YARN. For some reason
sbt dependencyTreeonmastershows thatcalcite-coreis excluded from thehive-execdependency tree, but the same command on this PR tries to resolvecalcite-core.Let me know if you have any ideas here. My best idea right now is to just try to duplicate the excludes in
spark-parent.
