Matt Foley commented on SPARK-21544:
------------------------------------
The problem described in detail in the Description above, regarding
spark-streaming module failing deploy due to duplicate attachment of the shaded
test jar, was not fixed in the accepted patch (which nevertheless DID fix the
different but similar-looking problems with sql/catalyst and sql/core). It
still happens with v2.4.0, when attempting to deploy to an internal repository.
Unlike the other problems fixed here, the problem with spark-streaming is not
due to bugs in spark project poms. Rather, its root cause is MSHADE-259, which
I'm in process of providing a PR for. I was also unable to find a work-around
that could be done from within spark project poms.
For those users needing to deploy shaded test jars to internal repos, hopefully
the maven-shade-plugin team will publish a fixed release soon. Until then, you
might consider using a private build of maven-shade-plugin, with the patch from
MSHADE-259. It turns out to be pretty simple to do.
