> Maven-shade-plugin only relocate java classes, but not Scala classes. I try
> to decompile flink-table jar, and find those guava path not beed relocated on
> those Scala classes. But flink job run normally for all time. Because
> flink-dist_${scala.binary.version}.jar contains the google guava and flink
> shaded guava at the same time. Why is the google guava still contained int
> the flink?
> Because we build flink by Maven-assembly-plugin at flink-disk module. The
> Assembly Plugin aggregate its all dependencies, includes those dependencies
> which are shaded now. If we use the following patch which exclude the Guava,
> then the flink-dist_${scala.binary.version}.jar only contains the
> flink-shaded-guava, not the google guava.
