Hi again
Why does it seem to me that everything Hadoop 0.23-related is an uphill
battle? :-(
I'm trying something as simple as running a classic(MapReduce 1) Hadoop
cluster. Here's my configuration:
core-site.xml:
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://samplehost.com:9000</value>
</property>
</configuration>
hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>3</value>
</property>
</configuration>
mapred-site.xml
<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>classic</value>
</property>
<property>
<name>mapred.job.tracker</name>
<value>samplehost.com:9001</value>
</property>
<property>
<name> mapreduce.jobtracker.address</name>
<value>samplehost.com:9001</value>
</property>
</configuration>
yarn-site.xml
<configuration>
</configuration>
Well, I start the thing and do a netstat -l , and there's no one
listening on port 9001. There are no errors in the logs, and no mention
of that port, either.
Obviously, all Map/Reduce examples fail with Connection Refused.
Starting the same cluster using a MapReduce 2 (YARN) configuration works
properly.

Alexander
