Duo Zhang commented on HBASE-26643:
-----------------------------------
OK, finally I find out that, on master branch, all the LoadBalancer are wrapped
with RSGroupBasedLoadBalancer and it will handle the case where there is no
server then it will put all the regions to BOGUS_SERVER_NAME...
> TestCreateTableWithMasterFailover and TestTruncateTableWithMasterFailover are
> flaky

> After HBASE-26641, these two tests are still flaky, they also fail for me

> After digging, I found that, while we see this in the log output after master
> failover
> {noformat}
> Wanted to do round robin assignment but no servers to assign to
> {noformat}
> The UTs will fail.
> Need to dig more.
