Description

ext hs2_port is binded by others process cause impalad exit , but before this impalad already registed to statestore , this node had been join query ， query always exception with impala not ready for query ( our cluster use Process monitoring program ， cause impala Always restart)

In my opinion impalad should promise local service start normal ， then Registering information to statetore 。 participating in the distributed queries

the code in impalad-main.cc

should like this

// this blocks until the beeswax and hs2 servers terminate
ABORT_IF_ERROR(beeswax_server->Start());
ABORT_IF_ERROR(hs2_server->Start());
ABORT_IF_ERROR(be_server->Start());

Status status = exec_env.StartServices();
if (!status.ok())

{ LOG(ERROR) << "Impalad services did not start correctly, exiting. Error: " << status.GetDetail(); ShutdownLogging(); exit(1); }
