             Summary: Fix bind exceptions in TestRenameWhileOpen and TestPendingInvalidateBlock
                 Key: HDFS-11134
                 URL: https://issues.apache.org/jira/browse/HDFS-11134
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin


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.)

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 shuld do for test {{TestPendingInvalidateBlock}}.
