>
> I found two bind exceptions causing the unit tests fails in history Jenkins
> buildings. One is test {{TestRenameWhileOpen}}, the other one is
> {{TestPendingInvalidateBlock}}.
> Here are the stack infos of {{TestRenameWhileOpen}}(I can't find the stack
> infos of {{TestPendingInvalidateBlock}} now since the time of that happened
> is too early, but I'm sure it has failed due to bind exception.)
> {code}
> java.net.BindException: Problem binding to [localhost:42155]

> Here specifying the namenode port is not necessary, is similar to HDFS-11129.
> And I have run this test many times in my local, it all passed. The same we
