--------------------------------
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.)
{code}
java.net.BindException: Problem binding to [localhost:42155]
java.net.BindException: Address already in use; For more details see:

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}}.
