Cannot resolve Datonode address in slave file

["Puri, Aseem" <As...@Honeywell.com>]

Hi

            I have a small Hadoop cluster with 3 machines. One is my
NameNode/JobTracker + DataNode/TaskTracker and other 2 are
DataNode/TaskTracker. So I have made all 3 as slave. 

 

In slave file I have put names of all there machines as:

 

master

slave

slave1

 

When I start Hadoop cluster it always start DataNode/TaskTracker on last
slave in the list and do not start DataNode/TaskTracker on other two
machines. Also I got the message as:

 

slave1:

: no address associated with name

: no address associated with name

slave1: starting datanode, logging to
/home/HadoopAdmin/hadoop/bin/../logs/hadoo

p-HadoopAdmin-datanode-ie11dtxpficbfise.out

 

If I change the order in slave file like this:

 

slave

slave1

master

 

then DataNode/TaskTracker on master m/c starts and not on other two.

 

Please tell how I should solve this problem.
