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.
