Examples with CoprocessorServiceRequest org.apache.hadoop.hbase.shaded.protobuf.generated.ClientProtos.CoprocessorServiceRequest used on opensource projects

Example 1 with CoprocessorServiceRequest

use of org.apache.hadoop.hbase.shaded.protobuf.generated.ClientProtos.CoprocessorServiceRequest in project hbase by apache.

the class HBaseAdmin method coprocessorService.

            // TODO: Are we retrying here? Does not seem so. We should use RetryingRpcCaller
            // TODO: Make this same as RegionCoprocessorRpcChannel and MasterCoprocessorRpcChannel. They
            // are all different though should do same thing; e.g. RpcChannel setup.
