Hi Istvan Wondering if you have faced similar errors?
When trying to use/integrate phoenix-client-hbase-1.6-4.16.0.jar in a multi-module project which includes other jars/dependencies from hbase, hadoop and more on the classpath Getting the following error when trying to create a connection I have narrowed it down to a couple of jars that are offending although not completely sure why (perhaps class loading issues?) hbase-client-xxxx.jar hbase-protocol-xxxx.jar Error: Can't find method newStub in org.apache.phoenix.coprocessor.generated.MetaDataProtos$MetaDataService!
