Mingliang Liu commented on HDFS-9407:
-------------------------------------
{code}
- .nameNodePort(HdfsClientConfigKeys.DFS_NAMENODE_RPC_PORT_DEFAULT)
+ .nameNodePort(
+ ServerSocketUtil.getPort(
+ HdfsClientConfigKeys.DFS_NAMENODE_RPC_PORT_DEFAULT, 10))
{code}
I don't think it's necessary to specify the name node RPC port. Even if we try
a specific port multiple times (here _10_), port binding conflict still has a
chance to happen. There should not be any logic in the test that depends on the
port number.
