主题： 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
org/apache/hadoop/hbase/util/CoprocessorClassLoader) of the current class,
org/apache/eagle/storage/hbase/query/coprocessor/AggregateProtocolEndPoint, and
the class loader (instance of sun/misc/Launcher$AppClassLoader) for i
nterface org/apache/hadoop/hbase/coprocessor/CoprocessorService have different
Class objects for the type
uery.coprocessor.AggregateProtocolEndPoint.getService()Lcom/google/protobuf/Service;

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!
