--------------------------------------

             Summary: RpcRetryingCallerFactory uses the conf for each "newCaller"

                 URL: https://issues.apache.org/jira/browse/HBASE-9990
             Project: HBase
          Issue Type: Bug
          Components: Client
    Affects Versions: 0.96.0, 0.98.0
            Reporter: Nicolas Liochon
            Assignee: Nicolas Liochon
             Fix For: 0.98.0, 0.96.1


You can construct a RpcRetryingCallerFactory, but actually the conf is read for each call.
Reading the conf is obviously expensive, and a profiling session shows it. If we want to sent
hundreds of thousands of queries per second, we should not do that.

RpcRetryingCallerFactory.newCaller is called for each get, for example.
