Thanks for your answer. I did already take a look at the documentation. We have the following code snippet in our pom in flink-shade.
<artifactSet> <includes> <include>com.google.guava:guava</include> </includes> </artifactSet> <relocations> <relocation> <pattern>com.google</pattern> <shadedPattern>org.apache.flink.shaded.com.google</shadedPattern> </relocation> </relocations> I first thought that the includes specify a whitelist of the packages to be relocated, so from my understanding it would not be necessary to exclude protobuf explicitly. Nevertheless, even the following change doesn't work. <artifactSet> <includes> <include>com.google.guava:guava</include> </includes> <excludes> <exclude>com.google.protobuf:*</exclude> </excludes> </artifactSet> <relocations> <relocation> <pattern>com.google</pattern> <shadedPattern>org.apache.flink.shaded.com.google</shadedPattern> </relocation> </relocations> Making the relocation part more specific solves the problem. <relocation> <pattern>com.google.guava</pattern> <shadedPattern>org.apache.flink.shaded.com.google.guava</shadedPattern> </relocation> 2014-11-14 10:22 GMT+01:00 Stephan Ewen <[email protected]>: > Hey Sebastian! > > I think there are two approaches: > > - You can either shade the protobuf Classes as well > > - or you can exclude the ptotobuf namespace from shading.
