Subject Running up DataNode service in Master!
Date Tue, 27 May 2008 02:24:20 GMT

Regards,

I'm configuring my own HDFS:

etc/hosts

192.168.46.242 master.com
192.168.46.244 slave3.com


///MASTER MACHINE - master and slave...

1) masters

master.com

2) slaves

master.com
slave3.com

3) hadoop-site.xml

  <property>
    <name>fs.default.name</name>
    <value>hdfs://master.com:9527</value>
  </property>
  ...
  <property>
    <name>mapred.job.tracker</name>
    <value>master.com:9528</value>
  </property>
  ...
  <property>
     <name>dfs.replication</name>
     <value>2</value>
  </property>


///SLAVE MACHINE ... only slave
1) masters

 ---- EMPTY ---- (someone advice me!, it's truth?)

2) slaves

 ---- EMPTY ---- (and it?)

3) hadoop-site.xml

  <property>
    <name>fs.default.name</name>
    <value>hdfs://slave3.com:9527</value>
  </property>
  ...
  <property>
    <name>mapred.job.tracker</name>
    <value>slave3.com:9528</value>
  </property>
  ...
  <property>
     <name>dfs.replication</name>
     <value>2</value>
  </property>


THE PROBLEM...

In slave machine all services are on!
In master machine, DATANODE service apparently doesn't run up! but, all
service: namenode, secondarynode, jobtracker and tasktracker run up!

Thanks for ur help.
