Ok. I see.
I have that on all the nodes:
<configuration>
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>
<property>
<name>dfs.datanode.max.xcievers</name>
<value>4096</value>
</property>
</configuration>
And that on my master:
hadoop@node3:~$ /usr/local/jdk1.7.0_05/bin/jps
2219 NameNode
2630 Jps
30362 JobTracker
2652 DataNode
30273 TaskTracker
2392 SecondaryNameNode
I will update all the mapred-site.xml and re-start the cluster.
I will keep you posted shortly.
Thanks!
JM
