I have a exception when i run my code in flink cluster. I thing that the problem is a overlaping .jar files in exec time with maven.

I can run de code in local mode, but when i run de program in kafka client this produce a excetion to try load de "javax/manangent/MBeanServer".

this is the exception produced by de flink cluster:

java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/flink/runtime/execution/librarycache/FlinkUserCodeClassLoaders$ChildFirstClassLoader) previously initiated loading for a different type with name "javax/management/MBeanServer"

I think you need to update the Scala version suffix of the exclusion of the maven-shade-plugin. You are depending on Scala 2.11 dependencies but your are excluding Scala 2.10 dependencies. Changing them to

<exclude>org.apache.flink:flink-scala_2.11</exclude>

<exclude>org.apache.flink:flink-runtime_2.11</exclude>

<exclude>org.apache.flink:flink-optimizer_2.11</exclude>

<exclude>org.apache.flink:flink-clients_2.11</exclude>

<exclude>org.apache.flink:flink-avro_2.11</exclude>

<exclude>org.apache.flink:flink-examples-batch_2.11</exclude>

<exclude>org.apache.flink:flink-examples-streaming_2.11</exclude>

<exclude>org.apache.flink:flink-streaming-java_2.11</exclude>

should do the trick.
