----------------------------------------------------------------------------------------------------------------------------

                 Key: HADOOP-3564
                 URL: https://issues.apache.org/jira/browse/HADOOP-3564
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/hod
    Affects Versions: 0.18.0
            Reporter: Karam Singh


>From Jira: HADOOP-3283 which introduced new conf parameter dfs.datanode.ipc.address which
defaults to 50020.
When static dfs of hadoop version 0.18.0 running and its conf is not having dfs.datanode.ipc.address
specified, then datanode start with 50020 port for ipc, w
When we  use  hod allocate without using static dfs.datanode on some machine fails to come.
On further investigation  it has been found sometimes when torque provides list nodes, that
list also contain some static dfs node.
When hodring tries to start datanode on a machine where a static dfs datanode of hadoop 0.18.0
is running, hod's dynamic dfs datanode fails to come with exception -: java.net.BindException:
Problem binding to /0.0.0.0:50020 : Address already in use
beacuse hod provides ports for dfs.datanode.address and dfs.datanode.http.address.
