答复: clustering problem

[Zhang, Guibin]

You can delete the DFS local dir in the slave (The local dictionary should be 
${hadoop.tmp.dir}/dfs/) and try again.

Hi Guys,

I am having problems creating clusters on 2 machines

Machine configuration :
Master : OS: Fedora core 7
             hadoop-0.15.2

hadoop-site.xml listing

<configuration>
  <property>
    <name>fs.default.name</name>
    <value>anaconda:50001</value>
  </property>
  <property>
    <name>mapred.job.tracker</name>
    <value>anaconda:50002</value>
  </property>
  <property>
    <name>dfs.replication</name>
    <value>2</value>
  </property>
  <property>
    <name>dfs.secondary.info.port</name>
    <value>50003</value>
  </property>
  <property>
    <name>dfs.info.port</name>
    <value>50004</value>
  </property>
  <property>
    <name>mapred.job.tracker.info.port</name>
    <value>50005</value>
  </property>
  <property>
    <name>tasktracker.http.port</name>
    <value>50006</value>
  </property>
</configuration>

conf/masters
localhost

conf/slaves
anaconda
v-desktop

the datanode, namenode, secondarynamenode seems to be working fine on the
master but on slave this is not the case

slave
OS: Ubuntu

hadoop-site.xml listing

same as master

in the logs on slave machine I see this

2008-03-05 12:15:25,705 INFO org.apache.hadoop.metrics.jvm.JvmMetrics:

Can someone help me with this please.

Thanks
