About quick start issue

[YijianLiu]

When I run ./run_dist_server_mode_fs_tracker.sh to test, result is shown below:
Client 0 started.
[2022-12-04 17:22:05.842047] Server started.
[2022-12-04 17:22:05.842530] Server started.
Client 1 started.
Client 2 started.
Then it will always wait here and can't continue? I find the question is the code in function "test_node_iterate(g)" and it will wait on "ds = gl.Dataset(query)", what's the problem and I don't know how to solve this.

It seems that error on c++ host.cc which uses "gethostbyname", it gets host 0.0.2.104 but I think it may be 127.0.0.1? Since I change this to run pytorch/gcn
