Hi all,

I am using hadoop 1.0.0 running in Cygwin. I'm getting the following
error message when I try to run jobtracker.

12/01/30 17:18:21 FATAL mapred.JobTracker:
java.lang.IllegalArgumentException: Does not contain a valid host:port
authority: local
        at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:185)
        at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:151)
        at org.apache.hadoop.mapred.JobTracker.getAddress(JobTracker.java:2560)
        at org.apache.hadoop.mapred.JobTracker.<init>(JobTracker.java:2200)
        at org.apache.hadoop.mapred.JobTracker.<init>(JobTracker.java:2192)
        at org.apache.hadoop.mapred.JobTracker.<init>(JobTracker.java:2186)
        at org.apache.hadoop.mapred.JobTracker.startTracker(JobTracker.java:300)
        at org.apache.hadoop.mapred.JobTracker.startTracker(JobTracker.java:291)
        at org.apache.hadoop.mapred.JobTracker.main(JobTracker.java:4978)

I have configured my core-site.xml file to read:

<configuration>
 <property>
   <name>fs.default.name</name>
   <value>hdfs://namenode:8020</value>
 </property>
</configuration>

I have also tried using localhost in place of namenode and dropping
the port at the end. I'm unsure what the problem is, and how to fix
it. Any help much appreciated.

Thanks,
Ian

You need mapred.job.tracker property (in your mapred-site.xml commonly)

Ina,

Also, is "namenode" a valid alias for your namenode machine?

Kindest regards.
