Description

Running CI in node1, the test_scylla will connect to Scylla node in node0. However, there are many data races happened.

Below is part of the test log. `================== WARNING: ThreadSanitizer: data race (pid=14) Read of size 1 at 0x7b2c0007ff64 by thread T6:

@locke2833 Have we got any progress on this issue?

howjmay commented 4 years ago

@YingHan-Chen We have implemented keyspace name assigning in scyllaDB interface, so can we close this issue?
