> When running testcases without any code changes, the function testBalancerWithPinnedBlocks
in TestBalancer.java never succeeded. I tried to use Ubuntu 16.04 and redhat 7, maybe the
failure is not related to various linux environment. I am not sure if there is some bug in
this case or I used wrong environment and settings. Could anyone give some advice.
