Ismaël Mejía commented on BEAM-3492:
------------------------------------
[~mariagh] The reason of the error is that
beam-sdks-java-io-google-cloud-platform is leaking some dependencies into the
classpath in this particular case it is netty that conflicts with the version
provided by spark, so I 'forced' the Spark runner execution of the examples to
use the older version but this can have uninttended consequences.
I filled this JIRA for a proper fix from the Google's IO side BEAM-3519
And about the fact that clicking on the test changed it to 'passed' I also saw
that one, and I believe is Jenkins magic :), I seriously don't have any idea of
what is going on with that.
