eagle hbase Coprocessor class loader conflict
Hi, I add the eagle hbase coprocessor(AggregateProtocolEndPoint) to a hbase table, but it throws a class loader conflict,
Here is the error message:
coprocessor.CoprocessorHost: The coprocessor org.apache.eagle.storage.hbase.query.coprocessor.AggregateProtocolEndPoint threw java.lang.LinkageError: loader cons
traint violation in interface itable initialization: when resolving method "org.apache.eagle.storage.hbase.query.coprocessor.AggregateProtocolEndPoint.getService()Lcom/google/protobuf/Service;" the class loader (instance of

This is my command to register the coprocessor
./eagle-run-class.sh org.apache.eagle.storage.hbase.tools.CoprocessorTool -jar jars/eagle-topology-0.4.0-incubating-assembly.jar -localJar ../lib/topology/eagle-topology-0.4.0-incubating-assembly.jar -register org.apache.eagle.storage.hbase.query.coprocessor.AggregateProtocolEndPoint -table eagle_metric -config ../conf/core-site.xml
Thank you all!
