Subject SecondaryNameNode not connecting to NameNode : PriviledgedActionException
Date Mon, 04 Jun 2012 11:07:24 GMT
Hello. I'm facing a issue when trying to configure my SecondaryNameNode on a different machine
than my NameNode. When both are on the same machine everything works fine but after moving
the secondary to a new machine I get:

2012-05-28 09:57:36,832 ERROR org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException

Is there any configuration I'm missing? At this point my mapred-site.xml is very simple just:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>mapred.job.tracker</name>
    <value>hadoop00:9001</value>
  </property>
  <property>
    <name>mapred.system.dir</name>
    <value>/home/hadoop/mapred/system</value>
  </property>
  <property>
    <name>mapred.local.dir</name>
    <value>/home/hadoop/mapred/local</value>
  </property>
  <property>
    <name>mapred.jobtracker.taskScheduler</name>
    <value>org.apache.hadoop.mapred.FairScheduler</value>
  </property>
  <property>
    <name>mapred.fairscheduler.allocation.file</name>
    <value>/home/hadoop/hadoop/conf/fairscheduler.xml</value>
  </property>
</configuration>
