> In stress testing Impala on Kudu I've seen various RPC timeouts that turn out to be due to pauses on the client side. In particular, scenarios like https://issues.cloudera.org/browse/IMPALA-2800 can cause the memory allocator inside Impala to block for several seconds, and that might cause us to think we missed a timeout.
> We should be more resilient to this sort of "false" timeout.
