Subject [jira] [Commented] (HDFS-9407) TestFileTruncate fails with BindException
Date Wed, 18 Nov 2015 06:33:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15010348#comment-15010348
] 

Walter Su commented on HDFS-9407:
---------------------------------

I think the point of specifically setting a RPC port, is to keep the port when cluster restarts.
We can do it by
{code}
  static void restartCluster(StartupOption o)
      throws IOException {
..
  final int nnport = cluster.getNameNodePort();
  cluster = new MiniDFSCluster.Builder(conf).nameNodePort(nnport)....
{code}
