Change subject: IMPALA-6116: Bound memory usage of DataStreamSevice's service queue ...................................................................... Patch Set 3: (2 comments) > Patch Set 1: > > (6 comments) > > I went through the change and found that I would prefer to not access > dependencies through the ExecEnv singleton, but instead inject them through > the ctors and Init(). That way it feels easier to me to follow the code. I > don't feel strongly about it though. I'm curious how do others feel about this? > > However, if we want to go with ExecEnv, we should probably remove some of the > injected dependencies as well to keep it consistent. http://gerrit.cloudera.org:8080/#/c/9282/1/be/src/rpc/rpc-mgr-test-base.h File be/src/rpc/rpc-mgr-test-base.h: http://gerrit.cloudera.org:8080/#/c/9282/1/be/src/rpc/rpc-mgr-test-base.h@133 PS1, Line 133: // Takes over ownership of the newly created 'service' which needs to have a lifetime > The RpcMgr no longer owns the rpc service.
