             Summary: New async admin api to invoke coproc on multiple servers
                 Key: HBASE-27902
                 URL: https://issues.apache.org/jira/browse/HBASE-27902
             Project: HBase
          Issue Type: Improvement
            Reporter: Viraj Jasani
            Assignee: Jing Yu


We can execute regionserver coproc on a given regionserver using:
{code:java}
<S, R> CompletableFuture<R> coprocessorService(Function<RpcChannel, S> stubMaker,
  ServiceCaller<S, R> callable, ServerName serverName); {code}
We should also provide an api at admin layer that can invoke the given coproc endpoint on multiple servers, to help execute the given function in parallel across the entire cluster.
